Find LCM of 545,638,520,572 with Prime Factorization


2 545, 638, 520, 572
2 545, 319, 260, 286
5 545, 319, 130, 143
11 109, 319, 26, 143
13 109, 29, 26, 13
109, 29, 2, 1

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

2 x 2 x 5 x 11 x 13 x 109 x 29 x 2 x 1 = 18080920

Therefore, the lowest common multiple of 545,638,520,572 is 18080920.

LCM Formula to Find Lowest Common Multiple of 545,638,520,572

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.

545 x 638 x 520 x 572 = 103422862400

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.

545 : 1, 5, 109, 545

638 : 1, 2, 11, 22, 29, 58, 319, 638

520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 545,638,520,572, is 1.

Now, the common factors can be found like this.

545:5x 109

638:2x 11x 29

520:2x 2x 2x 5x 13

572:2x 2x 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 2x 2x 5x 11x 13 = 5720

Therefore, the value for common factors is 5720.

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 = 103422862400/(1x5720)

LCM = 103422862400/5720

LCM = 18080920

Thus, we can understand that the LCM of 545,638,520,572 is 18080920.
