Given numbers are 749,390,122,668

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

The LCM of 749,390,122,668 is 5951449140.

Find LCM of 749,390,122,668 with Prime Factorization

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

2 x 749 x 195 x 61 x 334 = 5951449140

Therefore, the lowest common multiple of 749,390,122,668 is 5951449140.

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.

749 x 390 x 122 x 668 = 23805796560

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.

749 : 1, 7, 107, 749

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

122 : 1, 2, 61, 122

668 : 1, 2, 4, 167, 334, 668

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,390,122,668, is 1.

Now, the common factors can be found like this.

749:7x 107

390:2x 3x 5x 13

122:2x 61

668:2x 2x 167

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 23805796560/(1x4)

LCM = 23805796560/4

LCM = 5951449140

Thus, we can understand that the LCM of 749,390,122,668 is 5951449140.
