Given numbers are 143,534,398,421

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

The LCM of 143,534,398,421 is 6397531998.

Find LCM of 143,534,398,421 with Prime Factorization

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

2 x 143 x 267 x 199 x 421 = 6397531998

Therefore, the lowest common multiple of 143,534,398,421 is 6397531998.

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.

143 x 534 x 398 x 421 = 12795063996

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.

143 : 1, 11, 13, 143

534 : 1, 2, 3, 6, 89, 178, 267, 534

398 : 1, 2, 199, 398

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 143,534,398,421, is 1.

Now, the common factors can be found like this.

143:11x 13

534:2x 3x 89

398:2x 199

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.

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 = 12795063996/(1x2)

LCM = 12795063996/2

LCM = 6397531998

Thus, we can understand that the LCM of 143,534,398,421 is 6397531998.
