Given numbers are 708,546,173,420

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

The LCM of 708,546,173,420 is 55730220.

Find LCM of 708,546,173,420 with Prime Factorization

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

2 x 2 x 3 x 7 x 59 x 13 x 173 x 5 = 55730220

Therefore, the lowest common multiple of 708,546,173,420 is 55730220.

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.

708 x 546 x 173 x 420 = 28088030880

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.

708 : 1, 2, 3, 4, 6, 12, 59, 118, 177, 236, 354, 708

546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546

173 : 1, 173

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 708,546,173,420, is 1.

Now, the common factors can be found like this.

708:2x 2x 3x 59

546:2x 3x 7x 13

173:173

420:2x 2x 3x 5x 7

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 3x 3x 7 = 504

Therefore, the value for common factors is 504.

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 = 28088030880/(1x504)

LCM = 28088030880/504

LCM = 55730220

Thus, we can understand that the LCM of 708,546,173,420 is 55730220.
