The LCM of 424,245,156,931 is 76975080.

Find LCM of 424,245,156,931 with Prime Factorization


2 424, 245, 156, 931
2 212, 245, 78, 931
7 106, 245, 39, 931
7 106, 35, 39, 133
106, 5, 39, 19

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

2 x 2 x 7 x 7 x 106 x 5 x 39 x 19 = 76975080

Therefore, the lowest common multiple of 424,245,156,931 is 76975080.

LCM Formula to Find Lowest Common Multiple of 424,245,156,931

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.

424 x 245 x 156 x 931 = 15087115680

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.

424 : 1, 2, 4, 8, 53, 106, 212, 424

245 : 1, 5, 7, 35, 49, 245

156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156

931 : 1, 7, 19, 49, 133, 931

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 424,245,156,931, is 1.

Now, the common factors can be found like this.

424:2x 2x 2x 53

245:5x 7x 7

156:2x 2x 3x 13

931:7x 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 7 = 196

Therefore, the value for common factors is 196.

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 = 15087115680/(1x196)

LCM = 15087115680/196

LCM = 76975080

Thus, we can understand that the LCM of 424,245,156,931 is 76975080.
