Given numbers are 421,620,452,364,857

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

The LCM of 421,620,452,364,857 is 2300246841620.

Find LCM of 421,620,452,364,857 with Prime Factorization

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

2 x 2 x 421 x 155 x 113 x 91 x 857 = 2300246841620

Therefore, the lowest common multiple of 421,620,452,364,857 is 2300246841620.

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.

421 x 620 x 452 x 364 x 857 = 36803949465920

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.

421 : 1, 421

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

452 : 1, 2, 4, 113, 226, 452

364 : 1, 2, 4, 7, 13, 14, 26, 28, 52, 91, 182, 364

857 : 1, 857

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,620,452,364,857, is 1.

Now, the common factors can be found like this.

421:421

620:2x 2x 5x 31

452:2x 2x 113

364:2x 2x 7x 13

857:857

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

2x 2x 2x 2 = 16

Therefore, the value for common factors is 16.

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 = 36803949465920/(1x16)

LCM = 36803949465920/16

LCM = 2300246841620

Thus, we can understand that the LCM of 421,620,452,364,857 is 2300246841620.
