Find LCM of 688,646,646,722,877 with Prime Factorization


2 688, 646, 646, 722, 877
17 344, 323, 323, 361, 877
19 344, 19, 19, 361, 877
344, 1, 1, 19, 877

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

2 x 17 x 19 x 344 x 1 x 1 x 19 x 877 = 3702918512

Therefore, the lowest common multiple of 688,646,646,722,877 is 3702918512.

LCM Formula to Find Lowest Common Multiple of 688,646,646,722,877

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 646 x 646 x 722 x 877 = 181798487265152

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

646 : 1, 2, 17, 19, 34, 38, 323, 646

646 : 1, 2, 17, 19, 34, 38, 323, 646

722 : 1, 2, 19, 38, 361, 722

877 : 1, 877

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 688,646,646,722,877, is 1.

Now, the common factors can be found like this.

688:2x 2x 2x 2x 43

646:2x 17x 19

646:2x 17x 19

722:2x 19x 19

877:877

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 17x 19x 19 = 49096

Therefore, the value for common factors is 49096.

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 = 181798487265152/(1x49096)

LCM = 181798487265152/49096

LCM = 3702918512

Thus, we can understand that the LCM of 688,646,646,722,877 is 3702918512.
