Given numbers are 720,129,584,641

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

The LCM of 720,129,584,641 is 1448711280.

Find LCM of 720,129,584,641 with Prime Factorization

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

2 x 2 x 2 x 3 x 30 x 43 x 73 x 641 = 1448711280

Therefore, the lowest common multiple of 720,129,584,641 is 1448711280.

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.

720 x 129 x 584 x 641 = 34769070720

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.

720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720

129 : 1, 3, 43, 129

584 : 1, 2, 4, 8, 73, 146, 292, 584

641 : 1, 641

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,129,584,641, is 1.

Now, the common factors can be found like this.

720:2x 2x 2x 2x 3x 3x 5

129:3x 43

584:2x 2x 2x 73

641:641

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 3 = 24

Therefore, the value for common factors is 24.

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 = 34769070720/(1x24)

LCM = 34769070720/24

LCM = 1448711280

Thus, we can understand that the LCM of 720,129,584,641 is 1448711280.
