Given numbers are 990,672,740,655

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

The LCM of 990,672,740,655 is 537435360.

Find LCM of 990,672,740,655 with Prime Factorization

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

2 x 2 x 3 x 5 x 33 x 56 x 37 x 131 = 537435360

Therefore, the lowest common multiple of 990,672,740,655 is 537435360.

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.

990 x 672 x 740 x 655 = 322461216000

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.

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

672 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 32, 42, 48, 56, 84, 96, 112, 168, 224, 336, 672

740 : 1, 2, 4, 5, 10, 20, 37, 74, 148, 185, 370, 740

655 : 1, 5, 131, 655

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 990,672,740,655, is 1.

Now, the common factors can be found like this.

990:2x 3x 3x 5x 11

672:2x 2x 2x 2x 2x 3x 7

740:2x 2x 5x 37

655:5x 131

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 3x 5x 5 = 600

Therefore, the value for common factors is 600.

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 = 322461216000/(1x600)

LCM = 322461216000/600

LCM = 537435360

Thus, we can understand that the LCM of 990,672,740,655 is 537435360.
