Given numbers are 420,746,402,437

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

The LCM of 420,746,402,437 is 4586848140.

Find LCM of 420,746,402,437 with Prime Factorization

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

2 x 3 x 70 x 373 x 67 x 437 = 4586848140

Therefore, the lowest common multiple of 420,746,402,437 is 4586848140.

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.

420 x 746 x 402 x 437 = 55042177680

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.

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

746 : 1, 2, 373, 746

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

437 : 1, 19, 23, 437

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,746,402,437, is 1.

Now, the common factors can be found like this.

420:2x 2x 3x 5x 7

746:2x 373

402:2x 3x 67

437:19x 23

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 3 = 12

Therefore, the value for common factors is 12.

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 = 55042177680/(1x12)

LCM = 55042177680/12

LCM = 4586848140

Thus, we can understand that the LCM of 420,746,402,437 is 4586848140.
