 ## How to find the Least Common Multiple of 39 and 50?

On this page below, we'll use the Prime Factorisation, and the List of Multiples method to find out the LCM of 39 and 50.

Follow the steps below, and let's calculate the LCM of 39 and 50.

### Method 1 - Prime factorization

#### Step 1: Create a list of all the prime factors of the numbers 39 and 50:

##### Prime factors of 39

The prime factors of 39 are 3 and 13. Prime factorization of 39 in exponential form is:

39 = 31x131

##### Prime factors of 50

The prime factors of 50 are 2, 5 and 5. Prime factorization of 50 in exponential form is:

50 = 21x52

31, 131, 21, 52

#### Step 3: Multiply these values together:

31x131x21x52=1950

#### Step 4: The result:

As seen on the calculation above, we have now obtained the LCM of 39 and 50.

The Least Common Multiple of 39 and 50 is 1950.

### Method 2 - List of Multiples

Find and list multiples of each number until the first common multiple is found. This is the lowest common multiple.

#### Multiples of 39:

39, 78, 117, 156, 195, 234, 273, 312, 351, 390, 429, 468, 507, 546, 585, 624, 663, 702, 741, 780, 819, 858, 897, 936, 975, 1014, 1053, 1092, 1131, 1170, 1209, 1248, 1287, 1326, 1365, 1404, 1443, 1482, 1521, 1560, 1599, 1638, 1677, 1716, 1755, 1794, 1833, 1872, 1911, 1950, 1989, 2028, 2067

#### Multiples of 50:

50, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1000, 1050, 1100, 1150, 1200, 1250, 1300, 1350, 1400, 1450, 1500, 1550, 1600, 1650, 1700, 1750, 1800, 1850, 1900, 1950, 2000, 2050, 2100

#### Therefore,

LCM(39, 50) = 1950
