Given numbers are 421,854,469,402

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

The LCM of 421,854,469,402 is 72266334.

Find LCM of 421,854,469,402 with Prime Factorization

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

2 x 7 x 67 x 421 x 61 x 1 x 3 = 72266334

Therefore, the lowest common multiple of 421,854,469,402 is 72266334.

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 854 x 469 x 402 = 67785821292

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

854 : 1, 2, 7, 14, 61, 122, 427, 854

469 : 1, 7, 67, 469

402 : 1, 2, 3, 6, 67, 134, 201, 402

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,854,469,402, is 1.

Now, the common factors can be found like this.

421:421

854:2x 7x 61

469:7x 67

402:2x 3x 67

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

2x 7x 67 = 938

Therefore, the value for common factors is 938.

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 = 67785821292/(1x938)

LCM = 67785821292/938

LCM = 72266334

Thus, we can understand that the LCM of 421,854,469,402 is 72266334.
