Given numbers are 712,403,917,845,421

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

The LCM of 712,403,917,845,421 is 7200287337880.

Find LCM of 712,403,917,845,421 with Prime Factorization

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

13 x 712 x 31 x 917 x 65 x 421 = 7200287337880

Therefore, the lowest common multiple of 712,403,917,845,421 is 7200287337880.

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.

712 x 403 x 917 x 845 x 421 = 93603735392440

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.

712 : 1, 2, 4, 8, 89, 178, 356, 712

403 : 1, 13, 31, 403

917 : 1, 7, 131, 917

845 : 1, 5, 13, 65, 169, 845

421 : 1, 421

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,403,917,845,421, is 1.

Now, the common factors can be found like this.

712:2x 2x 2x 89

403:13x 31

917:7x 131

845:5x 13x 13

421:421

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

13 = 13

Therefore, the value for common factors is 13.

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 = 93603735392440/(1x13)

LCM = 93603735392440/13

LCM = 7200287337880

Thus, we can understand that the LCM of 712,403,917,845,421 is 7200287337880.
