Given numbers are 661,602,306,638

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

The LCM of 661,602,306,638 is 19421379054.

Find LCM of 661,602,306,638 with Prime Factorization

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

2 x 661 x 301 x 153 x 319 = 19421379054

Therefore, the lowest common multiple of 661,602,306,638 is 19421379054.

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.

661 x 602 x 306 x 638 = 77685516216

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.

661 : 1, 661

602 : 1, 2, 7, 14, 43, 86, 301, 602

306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306

638 : 1, 2, 11, 22, 29, 58, 319, 638

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,602,306,638, is 1.

Now, the common factors can be found like this.

661:661

602:2x 7x 43

306:2x 3x 3x 17

638:2x 11x 29

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 = 77685516216/(1x4)

LCM = 77685516216/4

LCM = 19421379054

Thus, we can understand that the LCM of 661,602,306,638 is 19421379054.
