Given numbers are 732,691,639,420

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

The LCM of 732,691,639,420 is 3770828460.

Find LCM of 732,691,639,420 with Prime Factorization

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

2 x 2 x 3 x 61 x 691 x 213 x 35 = 3770828460

Therefore, the lowest common multiple of 732,691,639,420 is 3770828460.

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.

732 x 691 x 639 x 420 = 135749824560

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.

732 : 1, 2, 3, 4, 6, 12, 61, 122, 183, 244, 366, 732

691 : 1, 691

639 : 1, 3, 9, 71, 213, 639

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 732,691,639,420, is 1.

Now, the common factors can be found like this.

732:2x 2x 3x 61

691:691

639:3x 3x 71

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 3x 3 = 36

Therefore, the value for common factors is 36.

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 = 135749824560/(1x36)

LCM = 135749824560/36

LCM = 3770828460

Thus, we can understand that the LCM of 732,691,639,420 is 3770828460.
