Given numbers are 648,985,980,418

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

The LCM of 648,985,980,418 is 6536625480.

Find LCM of 648,985,980,418 with Prime Factorization

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

2 x 2 x 5 x 162 x 197 x 49 x 209 = 6536625480

Therefore, the lowest common multiple of 648,985,980,418 is 6536625480.

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.

648 x 985 x 980 x 418 = 261465019200

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.

648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648

985 : 1, 5, 197, 985

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

418 : 1, 2, 11, 19, 22, 38, 209, 418

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 648,985,980,418, is 1.

Now, the common factors can be found like this.

648:2x 2x 2x 3x 3x 3x 3

985:5x 197

980:2x 2x 5x 7x 7

418:2x 11x 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 2x 2x 5 = 40

Therefore, the value for common factors is 40.

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 = 261465019200/(1x40)

LCM = 261465019200/40

LCM = 6536625480

Thus, we can understand that the LCM of 648,985,980,418 is 6536625480.
