Calculate the LCM of 637,681,578,130

Given numbers are 637,681,578,130

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

The LCM of 637,681,578,130 is 1253673330.

Find LCM of 637,681,578,130 with Prime Factorization


2 637, 681, 578, 130
13 637, 681, 289, 65
49, 681, 289, 5

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

2 x 13 x 49 x 681 x 289 x 5 = 1253673330

Therefore, the lowest common multiple of 637,681,578,130 is 1253673330.

LCM Formula to Find Lowest Common Multiple of 637,681,578,130

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.

637 x 681 x 578 x 130 = 32595506580

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.

637 : 1, 7, 13, 49, 91, 637

681 : 1, 3, 227, 681

578 : 1, 2, 17, 34, 289, 578

130 : 1, 2, 5, 10, 13, 26, 65, 130

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,681,578,130, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

681:3x 227

578:2x 17x 17

130:2x 5x 13

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

2x 13 = 26

Therefore, the value for common factors is 26.

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 = 32595506580/(1x26)

LCM = 32595506580/26

LCM = 1253673330

Thus, we can understand that the LCM of 637,681,578,130 is 1253673330.
