Given numbers are 731,142,749,620

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

The LCM of 731,142,749,620 is 24101786380.

Find LCM of 731,142,749,620 with Prime Factorization

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

2 x 731 x 71 x 749 x 310 = 24101786380

Therefore, the lowest common multiple of 731,142,749,620 is 24101786380.

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.

731 x 142 x 749 x 620 = 48203572760

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.

731 : 1, 17, 43, 731

142 : 1, 2, 71, 142

749 : 1, 7, 107, 749

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 731,142,749,620, is 1.

Now, the common factors can be found like this.

731:17x 43

142:2x 71

749:7x 107

620:2x 2x 5x 31

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

2 = 2

Therefore, the value for common factors is 2.

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 = 48203572760/(1x2)

LCM = 48203572760/2

LCM = 24101786380

Thus, we can understand that the LCM of 731,142,749,620 is 24101786380.
