Given numbers are 975,143,637,838

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

The LCM of 975,143,637,838 is 440389950.

Find LCM of 975,143,637,838 with Prime Factorization

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

13 x 75 x 11 x 49 x 838 = 440389950

Therefore, the lowest common multiple of 975,143,637,838 is 440389950.

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.

975 x 143 x 637 x 838 = 74425901550

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.

975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975

143 : 1, 11, 13, 143

637 : 1, 7, 13, 49, 91, 637

838 : 1, 2, 419, 838

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 975,143,637,838, is 1.

Now, the common factors can be found like this.

975:3x 5x 5x 13

143:11x 13

637:7x 7x 13

838:2x 419

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

13x 13 = 169

Therefore, the value for common factors is 169.

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 = 74425901550/(1x169)

LCM = 74425901550/169

LCM = 440389950

Thus, we can understand that the LCM of 975,143,637,838 is 440389950.
