Given numbers are 665,428,902,142

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

The LCM of 665,428,902,142 is 9113817020.

Find LCM of 665,428,902,142 with Prime Factorization

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

2 x 665 x 214 x 451 x 71 = 9113817020

Therefore, the lowest common multiple of 665,428,902,142 is 9113817020.

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.

665 x 428 x 902 x 142 = 36455268080

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

428 : 1, 2, 4, 107, 214, 428

902 : 1, 2, 11, 22, 41, 82, 451, 902

142 : 1, 2, 71, 142

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,428,902,142, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

428:2x 2x 107

902:2x 11x 41

142:2x 71

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

2x 2 = 4

Therefore, the value for common factors is 4.

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 = 36455268080/(1x4)

LCM = 36455268080/4

LCM = 9113817020

Thus, we can understand that the LCM of 665,428,902,142 is 9113817020.
