Given numbers are 651,620,173,745

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

The LCM of 651,620,173,745 is 335616540.

Find LCM of 651,620,173,745 with Prime Factorization

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

5 x 31 x 21 x 4 x 173 x 149 = 335616540

Therefore, the lowest common multiple of 651,620,173,745 is 335616540.

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.

651 x 620 x 173 x 745 = 52020563700

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.

651 : 1, 3, 7, 21, 31, 93, 217, 651

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

173 : 1, 173

745 : 1, 5, 149, 745

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,620,173,745, is 1.

Now, the common factors can be found like this.

651:3x 7x 31

620:2x 2x 5x 31

173:173

745:5x 149

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

5x 31 = 155

Therefore, the value for common factors is 155.

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 = 52020563700/(1x155)

LCM = 52020563700/155

LCM = 335616540

Thus, we can understand that the LCM of 651,620,173,745 is 335616540.
