Given numbers are 807,122,408,980

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

The LCM of 807,122,408,980 is 1640243640.

Find LCM of 807,122,408,980 with Prime Factorization

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

2 x 2 x 3 x 269 x 61 x 34 x 245 = 1640243640

Therefore, the lowest common multiple of 807,122,408,980 is 1640243640.

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.

807 x 122 x 408 x 980 = 39365847360

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.

807 : 1, 3, 269, 807

122 : 1, 2, 61, 122

408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 807,122,408,980, is 1.

Now, the common factors can be found like this.

807:3x 269

122:2x 61

408:2x 2x 2x 3x 17

980:2x 2x 5x 7x 7

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 = 39365847360/(1x24)

LCM = 39365847360/24

LCM = 1640243640

Thus, we can understand that the LCM of 807,122,408,980 is 1640243640.
