Find LCM of 638,917,646,466,665 with Prime Factorization


2 638, 917, 646, 466, 665
7 319, 917, 323, 233, 665
19 319, 131, 323, 233, 95
319, 131, 17, 233, 5

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

2 x 7 x 19 x 319 x 131 x 17 x 233 x 5 = 220149884570

Therefore, the lowest common multiple of 638,917,646,466,665 is 220149884570.

LCM Formula to Find Lowest Common Multiple of 638,917,646,466,665

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.

638 x 917 x 646 x 466 x 665 = 117119738591240

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.

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

917 : 1, 7, 131, 917

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

466 : 1, 2, 233, 466

665 : 1, 5, 7, 19, 35, 95, 133, 665

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 638,917,646,466,665, is 1.

Now, the common factors can be found like this.

638:2x 11x 29

917:7x 131

646:2x 17x 19

466:2x 233

665:5x 7x 19

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 7x 19 = 532

Therefore, the value for common factors is 532.

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 = 117119738591240/(1x532)

LCM = 117119738591240/532

LCM = 220149884570

Thus, we can understand that the LCM of 638,917,646,466,665 is 220149884570.
