Find LCM of 872,208,624,961 with Prime Factorization


2 872, 208, 624, 961
2 436, 104, 312, 961
2 218, 52, 156, 961
2 109, 26, 78, 961
13 109, 13, 39, 961
109, 1, 3, 961

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

2 x 2 x 2 x 2 x 13 x 109 x 1 x 3 x 961 = 65363376

Therefore, the lowest common multiple of 872,208,624,961 is 65363376.

LCM Formula to Find Lowest Common Multiple of 872,208,624,961

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.

872 x 208 x 624 x 961 = 108764657664

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.

872 : 1, 2, 4, 8, 109, 218, 436, 872

208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624

961 : 1, 31, 961

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 872,208,624,961, is 1.

Now, the common factors can be found like this.

872:2x 2x 2x 109

208:2x 2x 2x 2x 13

624:2x 2x 2x 2x 3x 13

961:31x 31

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 2x 2x 2x 13 = 1664

Therefore, the value for common factors is 1664.

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 = 108764657664/(1x1664)

LCM = 108764657664/1664

LCM = 65363376

Thus, we can understand that the LCM of 872,208,624,961 is 65363376.
