Calculate the LCM of 749,374,765,638

Given numbers are 749,374,765,638

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

The LCM of 749,374,765,638 is 365564430.

Find LCM of 749,374,765,638 with Prime Factorization


2 749, 374, 765, 638
11 749, 187, 765, 319
17 749, 17, 765, 29
749, 1, 45, 29

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

2 x 11 x 17 x 749 x 1 x 45 x 29 = 365564430

Therefore, the lowest common multiple of 749,374,765,638 is 365564430.

LCM Formula to Find Lowest Common Multiple of 749,374,765,638

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.

749 x 374 x 765 x 638 = 136721096820

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.

749 : 1, 7, 107, 749

374 : 1, 2, 11, 17, 22, 34, 187, 374

765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765

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 749,374,765,638, is 1.

Now, the common factors can be found like this.

749:7x 107

374:2x 11x 17

765:3x 3x 5x 17

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 11x 17 = 374

Therefore, the value for common factors is 374.

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 = 136721096820/(1x374)

LCM = 136721096820/374

LCM = 365564430

Thus, we can understand that the LCM of 749,374,765,638 is 365564430.
