Given numbers are 985,121,221,611

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

The LCM of 985,121,221,611 is 1237974595.

Find LCM of 985,121,221,611 with Prime Factorization

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

13 x 985 x 121 x 17 x 47 = 1237974595

Therefore, the lowest common multiple of 985,121,221,611 is 1237974595.

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.

985 x 121 x 221 x 611 = 16093669735

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.

985 : 1, 5, 197, 985

121 : 1, 11, 121

221 : 1, 13, 17, 221

611 : 1, 13, 47, 611

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 985,121,221,611, is 1.

Now, the common factors can be found like this.

985:5x 197

121:11x 11

221:13x 17

611:13x 47

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

13 = 13

Therefore, the value for common factors is 13.

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 = 16093669735/(1x13)

LCM = 16093669735/13

LCM = 1237974595

Thus, we can understand that the LCM of 985,121,221,611 is 1237974595.
