Calculate the LCM of 671,740,280

Given numbers are 671,740,280

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

The LCM of 671,740,280 is 6951560.

Find LCM of 671,740,280 with Prime Factorization


2 671, 740, 280
2 671, 370, 140
5 671, 185, 70
671, 37, 14

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

2 x 2 x 5 x 671 x 37 x 14 = 6951560

Therefore, the lowest common multiple of 671,740,280 is 6951560.

LCM Formula to Find Lowest Common Multiple of 671,740,280

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.

671 x 740 x 280 = 139031200

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.

671 : 1, 11, 61, 671

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,740,280, is 1.

Now, the common factors can be found like this.

671:11x 61

740:2x 2x 5x 37

280:2x 2x 2x 5x 7

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

2x 2x 5 = 20

Therefore, the value for common factors is 20.

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 = 139031200/(1x20)

LCM = 139031200/20

LCM = 6951560

Thus, we can understand that the LCM of 671,740,280 is 6951560.
