Given numbers are 421,193,950,989,421

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

The LCM of 421,193,950,989,421 is 76341256150.

Find LCM of 421,193,950,989,421 with Prime Factorization

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

421 x 1 x 193 x 950 x 989 x 1 = 76341256150

Therefore, the lowest common multiple of 421,193,950,989,421 is 76341256150.

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.

421 x 193 x 950 x 989 x 421 = 32139668839150

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.

421 : 1, 421

193 : 1, 193

950 : 1, 2, 5, 10, 19, 25, 38, 50, 95, 190, 475, 950

989 : 1, 23, 43, 989

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,193,950,989,421, is 1.

Now, the common factors can be found like this.

421:421

193:193

950:2x 5x 5x 19

989:23x 43

421:421

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

421 = 421

Therefore, the value for common factors is 421.

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 = 32139668839150/(1x421)

LCM = 32139668839150/421

LCM = 76341256150

Thus, we can understand that the LCM of 421,193,950,989,421 is 76341256150.
