Calculate the LCM of 647,879,654,715

Given numbers are 647,879,654,715

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

The LCM of 647,879,654,715 is 88645295310.

Find LCM of 647,879,654,715 with Prime Factorization


3 647, 879, 654, 715
647, 293, 218, 715

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

3 x 647 x 293 x 218 x 715 = 88645295310

Therefore, the lowest common multiple of 647,879,654,715 is 88645295310.

LCM Formula to Find Lowest Common Multiple of 647,879,654,715

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.

647 x 879 x 654 x 715 = 265935885930

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.

647 : 1, 647

879 : 1, 3, 293, 879

654 : 1, 2, 3, 6, 109, 218, 327, 654

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 647,879,654,715, is 1.

Now, the common factors can be found like this.

647:647

879:3x 293

654:2x 3x 109

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.

3 = 3

Therefore, the value for common factors is 3.

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 = 265935885930/(1x3)

LCM = 265935885930/3

LCM = 88645295310

Thus, we can understand that the LCM of 647,879,654,715 is 88645295310.
