Given numbers are 746,649,376,420

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

The LCM of 746,649,376,420 is 9557199960.

Find LCM of 746,649,376,420 with Prime Factorization

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

2 x 2 x 373 x 649 x 94 x 105 = 9557199960

Therefore, the lowest common multiple of 746,649,376,420 is 9557199960.

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.

746 x 649 x 376 x 420 = 76457599680

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.

746 : 1, 2, 373, 746

649 : 1, 11, 59, 649

376 : 1, 2, 4, 8, 47, 94, 188, 376

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 746,649,376,420, is 1.

Now, the common factors can be found like this.

746:2x 373

649:11x 59

376:2x 2x 2x 47

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 2 = 8

Therefore, the value for common factors is 8.

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 = 76457599680/(1x8)

LCM = 76457599680/8

LCM = 9557199960

Thus, we can understand that the LCM of 746,649,376,420 is 9557199960.
