Calculate the LCM of 667,788,240,985

Given numbers are 667,788,240,985

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 667,788,240,985 is 31535760.

Find LCM of 667,788,240,985 with Prime Factorization


2 667, 788, 240, 985
2 667, 394, 120, 985
5 667, 197, 60, 985
197 667, 197, 12, 197
667, 1, 12, 1

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

2 x 2 x 5 x 197 x 667 x 1 x 12 x 1 = 31535760

Therefore, the lowest common multiple of 667,788,240,985 is 31535760.

LCM Formula to Find Lowest Common Multiple of 667,788,240,985

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.

667 x 788 x 240 x 985 = 124250894400

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.

667 : 1, 23, 29, 667

788 : 1, 2, 4, 197, 394, 788

240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,788,240,985, is 1.

Now, the common factors can be found like this.

667:23x 29

788:2x 2x 197

240:2x 2x 2x 2x 3x 5

985:5x 197

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 5x 197 = 3940

Therefore, the value for common factors is 3940.

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 = 124250894400/(1x3940)

LCM = 124250894400/3940

LCM = 31535760

Thus, we can understand that the LCM of 667,788,240,985 is 31535760.
