Given numbers are 672,709,440,730

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

The LCM of 672,709,440,730 is 1912938720.

Find LCM of 672,709,440,730 with Prime Factorization

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

2 x 2 x 2 x 5 x 84 x 709 x 11 x 73 = 1912938720

Therefore, the lowest common multiple of 672,709,440,730 is 1912938720.

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.

672 x 709 x 440 x 730 = 153035097600

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.

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

709 : 1, 709

440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440

730 : 1, 2, 5, 10, 73, 146, 365, 730

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 672,709,440,730, is 1.

Now, the common factors can be found like this.

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

709:709

440:2x 2x 2x 5x 11

730:2x 5x 73

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 2x 5 = 80

Therefore, the value for common factors is 80.

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 = 153035097600/(1x80)

LCM = 153035097600/80

LCM = 1912938720

Thus, we can understand that the LCM of 672,709,440,730 is 1912938720.
