Calculate the LCM of 572,695,645,781,781

Given numbers are 572,695,645,781,781

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

The LCM of 572,695,645,781,781 is 3641068860.

Find LCM of 572,695,645,781,781 with Prime Factorization


5 572, 695, 645, 781, 781
11 572, 139, 129, 781, 781
71 52, 139, 129, 71, 71
52, 139, 129, 1, 1

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

5 x 11 x 71 x 52 x 139 x 129 x 1 x 1 = 3641068860

Therefore, the lowest common multiple of 572,695,645,781,781 is 3641068860.

LCM Formula to Find Lowest Common Multiple of 572,695,645,781,781

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.

572 x 695 x 645 x 781 x 781 = 156402112881300

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.

572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572

695 : 1, 5, 139, 695

645 : 1, 3, 5, 15, 43, 129, 215, 645

781 : 1, 11, 71, 781

781 : 1, 11, 71, 781

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 572,695,645,781,781, is 1.

Now, the common factors can be found like this.

572:2x 2x 11x 13

695:5x 139

645:3x 5x 43

781:11x 71

781:11x 71

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

5x 11x 11x 71 = 42955

Therefore, the value for common factors is 42955.

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 = 156402112881300/(1x42955)

LCM = 156402112881300/42955

LCM = 3641068860

Thus, we can understand that the LCM of 572,695,645,781,781 is 3641068860.
