Given numbers are 646,237,720,767

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

The LCM of 646,237,720,767 is 14091508080.

Find LCM of 646,237,720,767 with Prime Factorization

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

2 x 3 x 323 x 79 x 120 x 767 = 14091508080

Therefore, the lowest common multiple of 646,237,720,767 is 14091508080.

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.

646 x 237 x 720 x 767 = 84549048480

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.

646 : 1, 2, 17, 19, 34, 38, 323, 646

237 : 1, 3, 79, 237

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

767 : 1, 13, 59, 767

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,237,720,767, is 1.

Now, the common factors can be found like this.

646:2x 17x 19

237:3x 79

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

767:13x 59

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3 = 6

Therefore, the value for common factors is 6.

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 = 84549048480/(1x6)

LCM = 84549048480/6

LCM = 14091508080

Thus, we can understand that the LCM of 646,237,720,767 is 14091508080.
