Given numbers are 647,273,968,880

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

The LCM of 647,273,968,880 is 1709788080.

Find LCM of 647,273,968,880 with Prime Factorization

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

2 x 2 x 2 x 11 x 647 x 273 x 11 x 10 = 1709788080

Therefore, the lowest common multiple of 647,273,968,880 is 1709788080.

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.

647 x 273 x 968 x 880 = 150461351040

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.

647 : 1, 647

273 : 1, 3, 7, 13, 21, 39, 91, 273

968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968

880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,273,968,880, is 1.

Now, the common factors can be found like this.

647:647

273:3x 7x 13

968:2x 2x 2x 11x 11

880:2x 2x 2x 2x 5x 11

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 11 = 88

Therefore, the value for common factors is 88.

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 = 150461351040/(1x88)

LCM = 150461351040/88

LCM = 1709788080

Thus, we can understand that the LCM of 647,273,968,880 is 1709788080.
