Calculate the LCM of 976,378,609,715

Given numbers are 976,378,609,715

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

The LCM of 976,378,609,715 is 3824861040.

Find LCM of 976,378,609,715 with Prime Factorization


2 976, 378, 609, 715
3 488, 189, 609, 715
7 488, 63, 203, 715
488, 9, 29, 715

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

2 x 3 x 7 x 488 x 9 x 29 x 715 = 3824861040

Therefore, the lowest common multiple of 976,378,609,715 is 3824861040.

LCM Formula to Find Lowest Common Multiple of 976,378,609,715

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.

976 x 378 x 609 x 715 = 160644163680

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.

976 : 1, 2, 4, 8, 16, 61, 122, 244, 488, 976

378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378

609 : 1, 3, 7, 21, 29, 87, 203, 609

715 : 1, 5, 11, 13, 55, 65, 143, 715

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 976,378,609,715, is 1.

Now, the common factors can be found like this.

976:2x 2x 2x 2x 61

378:2x 3x 3x 3x 7

609:3x 7x 29

715:5x 11x 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 3x 7 = 42

Therefore, the value for common factors is 42.

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 = 160644163680/(1x42)

LCM = 160644163680/42

LCM = 3824861040

Thus, we can understand that the LCM of 976,378,609,715 is 3824861040.
