Given numbers are 712,133,646,247

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

The LCM of 712,133,646,247 is 20927816.

Find LCM of 712,133,646,247 with Prime Factorization

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

2 x 19 x 356 x 7 x 17 x 13 = 20927816

Therefore, the lowest common multiple of 712,133,646,247 is 20927816.

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 133 x 646 x 247 = 15109883152

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

133 : 1, 7, 19, 133

646 : 1, 2, 17, 19, 34, 38, 323, 646

247 : 1, 13, 19, 247

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,133,646,247, is 1.

Now, the common factors can be found like this.

712:2x 2x 2x 89

133:7x 19

646:2x 17x 19

247:13x 19

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

2x 19x 19 = 722

Therefore, the value for common factors is 722.

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 = 15109883152/(1x722)

LCM = 15109883152/722

LCM = 20927816

Thus, we can understand that the LCM of 712,133,646,247 is 20927816.
