Calculate the LCM of 427,260,742,980

Given numbers are 427,260,742,980

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

The LCM of 427,260,742,980 is 41188420.

Find LCM of 427,260,742,980 with Prime Factorization


2 427, 260, 742, 980
2 427, 130, 371, 490
5 427, 65, 371, 245
7 427, 13, 371, 49
61, 13, 53, 7

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

2 x 2 x 5 x 7 x 61 x 13 x 53 x 7 = 41188420

Therefore, the lowest common multiple of 427,260,742,980 is 41188420.

LCM Formula to Find Lowest Common Multiple of 427,260,742,980

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.

427 x 260 x 742 x 980 = 80729303200

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.

427 : 1, 7, 61, 427

260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260

742 : 1, 2, 7, 14, 53, 106, 371, 742

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 427,260,742,980, is 1.

Now, the common factors can be found like this.

427:7x 61

260:2x 2x 5x 13

742:2x 7x 53

980:2x 2x 5x 7x 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 2x 5x 7x 7 = 1960

Therefore, the value for common factors is 1960.

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 = 80729303200/(1x1960)

LCM = 80729303200/1960

LCM = 41188420

Thus, we can understand that the LCM of 427,260,742,980 is 41188420.
