Find LCM of 688,553,329,716,780 with Prime Factorization


2 688, 553, 329, 716, 780
2 344, 553, 329, 358, 390
7 172, 553, 329, 179, 195
172, 79, 47, 179, 195

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

2 x 2 x 7 x 172 x 79 x 47 x 179 x 195 = 624164508240

Therefore, the lowest common multiple of 688,553,329,716,780 is 624164508240.

LCM Formula to Find Lowest Common Multiple of 688,553,329,716,780

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.

688 x 553 x 329 x 716 x 780 = 69906424922880

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.

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

553 : 1, 7, 79, 553

329 : 1, 7, 47, 329

716 : 1, 2, 4, 179, 358, 716

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,553,329,716,780, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

553:7x 79

329:7x 47

716:2x 2x 179

780:2x 2x 3x 5x 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 2x 2x 2x 7 = 112

Therefore, the value for common factors is 112.

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 = 69906424922880/(1x112)

LCM = 69906424922880/112

LCM = 624164508240

Thus, we can understand that the LCM of 688,553,329,716,780 is 624164508240.
