Given numbers are 426,471,143,380

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

The LCM of 426,471,143,380 is 1817183940.

Find LCM of 426,471,143,380 with Prime Factorization

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

2 x 3 x 71 x 157 x 143 x 190 = 1817183940

Therefore, the lowest common multiple of 426,471,143,380 is 1817183940.

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.

426 x 471 x 143 x 380 = 10903103640

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.

426 : 1, 2, 3, 6, 71, 142, 213, 426

471 : 1, 3, 157, 471

143 : 1, 11, 13, 143

380 : 1, 2, 4, 5, 10, 19, 20, 38, 76, 95, 190, 380

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 426,471,143,380, is 1.

Now, the common factors can be found like this.

426:2x 3x 71

471:3x 157

143:11x 13

380:2x 2x 5x 19

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

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 10903103640/(1x6)

LCM = 10903103640/6

LCM = 1817183940

Thus, we can understand that the LCM of 426,471,143,380 is 1817183940.
