Given numbers are 642,357,118,880

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

The LCM of 642,357,118,880 is 1983292080.

Find LCM of 642,357,118,880 with Prime Factorization

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

2 x 3 x 107 x 119 x 59 x 440 = 1983292080

Therefore, the lowest common multiple of 642,357,118,880 is 1983292080.

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.

642 x 357 x 118 x 880 = 23799504960

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.

642 : 1, 2, 3, 6, 107, 214, 321, 642

357 : 1, 3, 7, 17, 21, 51, 119, 357

118 : 1, 2, 59, 118

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 642,357,118,880, is 1.

Now, the common factors can be found like this.

642:2x 3x 107

357:3x 7x 17

118:2x 59

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 3 = 12

Therefore, the value for common factors is 12.

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 = 23799504960/(1x12)

LCM = 23799504960/12

LCM = 1983292080

Thus, we can understand that the LCM of 642,357,118,880 is 1983292080.
