Given numbers are 142,720,107

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 142,720,107 is 5469840.

Find LCM of 142,720,107 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 71 x 360 x 107 = 5469840

Therefore, the lowest common multiple of 142,720,107 is 5469840.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

142 x 720 x 107 = 10939680

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

142 : 1, 2, 71, 142

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

107 : 1, 107

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,720,107, is 1.

Now, the common factors can be found like this.

142:2x 71

720:2x 2x 2x 2x 3x 3x 5

107:107

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 10939680/(1x2)

LCM = 10939680/2

LCM = 5469840

Thus, we can understand that the LCM of 142,720,107 is 5469840.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 475, 615, 786
• LCM of 890, 765, 908
