The LCM of 627,646,913,474 is 139782126.

Find LCM of 627,646,913,474 with Prime Factorization


2 627, 646, 913, 474
3 627, 323, 913, 237
11 209, 323, 913, 79
19 19, 323, 83, 79
1, 17, 83, 79

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

2 x 3 x 11 x 19 x 1 x 17 x 83 x 79 = 139782126

Therefore, the lowest common multiple of 627,646,913,474 is 139782126.

LCM Formula to Find Lowest Common Multiple of 627,646,913,474

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.

627 x 646 x 913 x 474 = 175286786004

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.

627 : 1, 3, 11, 19, 33, 57, 209, 627

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

913 : 1, 11, 83, 913

474 : 1, 2, 3, 6, 79, 158, 237, 474

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 627,646,913,474, is 1.

Now, the common factors can be found like this.

627:3x 11x 19

646:2x 17x 19

913:11x 83

474:2x 3x 79

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 11x 19 = 1254

Therefore, the value for common factors is 1254.

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 = 175286786004/(1x1254)

LCM = 175286786004/1254

LCM = 139782126

Thus, we can understand that the LCM of 627,646,913,474 is 139782126.
