Given numbers are 673,390,977,749,436

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

The LCM of 673,390,977,749,436 is 41870924129580.

Find LCM of 673,390,977,749,436 with Prime Factorization

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

2 x 673 x 195 x 977 x 749 x 218 = 41870924129580

Therefore, the lowest common multiple of 673,390,977,749,436 is 41870924129580.

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.

673 x 390 x 977 x 749 x 436 = 83741848259160

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.

673 : 1, 673

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

977 : 1, 977

749 : 1, 7, 107, 749

436 : 1, 2, 4, 109, 218, 436

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 673,390,977,749,436, is 1.

Now, the common factors can be found like this.

673:673

390:2x 3x 5x 13

977:977

749:7x 107

436:2x 2x 109

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

2 = 2

Therefore, the value for common factors is 2.

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 = 83741848259160/(1x2)

LCM = 83741848259160/2

LCM = 41870924129580

Thus, we can understand that the LCM of 673,390,977,749,436 is 41870924129580.
