Given numbers are 621,691,902,691

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

The LCM of 621,691,902,691 is 387058122.

Find LCM of 621,691,902,691 with Prime Factorization

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

691 x 621 x 1 x 902 x 1 = 387058122

Therefore, the lowest common multiple of 621,691,902,691 is 387058122.

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.

621 x 691 x 902 x 691 = 267457162302

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.

621 : 1, 3, 9, 23, 27, 69, 207, 621

691 : 1, 691

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

691 : 1, 691

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,691,902,691, is 1.

Now, the common factors can be found like this.

621:3x 3x 3x 23

691:691

902:2x 11x 41

691:691

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

691 = 691

Therefore, the value for common factors is 691.

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 = 267457162302/(1x691)

LCM = 267457162302/691

LCM = 387058122

Thus, we can understand that the LCM of 621,691,902,691 is 387058122.
