Given numbers are 707,451,420

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

The LCM of 707,451,420 is 19131420.

Find LCM of 707,451,420 with Prime Factorization

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

7 x 101 x 451 x 60 = 19131420

Therefore, the lowest common multiple of 707,451,420 is 19131420.

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.

707 x 451 x 420 = 133919940

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.

707 : 1, 7, 101, 707

451 : 1, 11, 41, 451

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 707,451,420, is 1.

Now, the common factors can be found like this.

707:7x 101

451:11x 41

420:2x 2x 3x 5x 7

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

7 = 7

Therefore, the value for common factors is 7.

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 = 133919940/(1x7)

LCM = 133919940/7

LCM = 19131420

Thus, we can understand that the LCM of 707,451,420 is 19131420.
