Calculate the LCM of 968,715,221,985

Given numbers are 968,715,221,985

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

The LCM of 968,715,221,985 is 210719080.

Find LCM of 968,715,221,985 with Prime Factorization


5 968, 715, 221, 985
11 968, 143, 221, 197
13 88, 13, 221, 197
88, 1, 17, 197

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

5 x 11 x 13 x 88 x 1 x 17 x 197 = 210719080

Therefore, the lowest common multiple of 968,715,221,985 is 210719080.

LCM Formula to Find Lowest Common Multiple of 968,715,221,985

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.

968 x 715 x 221 x 985 = 150664142200

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.

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

715 : 1, 5, 11, 13, 55, 65, 143, 715

221 : 1, 13, 17, 221

985 : 1, 5, 197, 985

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 968,715,221,985, is 1.

Now, the common factors can be found like this.

968:2x 2x 2x 11x 11

715:5x 11x 13

221:13x 17

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.

5x 11x 13 = 715

Therefore, the value for common factors is 715.

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 = 150664142200/(1x715)

LCM = 150664142200/715

LCM = 210719080

Thus, we can understand that the LCM of 968,715,221,985 is 210719080.
