The LCM of 975,638,747,638 is 154890450.

Find LCM of 975,638,747,638 with Prime Factorization


2 975, 638, 747, 638
3 975, 319, 747, 319
11 325, 319, 249, 319
29 325, 29, 249, 29
325, 1, 249, 1

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

2 x 3 x 11 x 29 x 325 x 1 x 249 x 1 = 154890450

Therefore, the lowest common multiple of 975,638,747,638 is 154890450.

LCM Formula to Find Lowest Common Multiple of 975,638,747,638

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.

975 x 638 x 747 x 638 = 296460321300

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.

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

638 : 1, 2, 11, 22, 29, 58, 319, 638

747 : 1, 3, 9, 83, 249, 747

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,638,747,638, is 1.

Now, the common factors can be found like this.

975:3x 5x 5x 13

638:2x 11x 29

747:3x 3x 83

638:2x 11x 29

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

2x 3x 11x 29 = 1914

Therefore, the value for common factors is 1914.

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 = 296460321300/(1x1914)

LCM = 296460321300/1914

LCM = 154890450

Thus, we can understand that the LCM of 975,638,747,638 is 154890450.
