Given numbers are 980,842,618,626,688

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

The LCM of 980,842,618,626,688 is 6863401975920.

Find LCM of 980,842,618,626,688 with Prime Factorization

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

2 x 2 x 245 x 421 x 309 x 313 x 172 = 6863401975920

Therefore, the lowest common multiple of 980,842,618,626,688 is 6863401975920.

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.

980 x 842 x 618 x 626 x 688 = 219628863229440

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.

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

842 : 1, 2, 421, 842

618 : 1, 2, 3, 6, 103, 206, 309, 618

626 : 1, 2, 313, 626

688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,842,618,626,688, is 2.

Now, the common factors can be found like this.

980:2x 2x 5x 7x 7

842:2x 421

618:2x 3x 103

626:2x 313

688:2x 2x 2x 2x 43

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 2 = 16

Therefore, the value for common factors is 16.

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 = 219628863229440/(2x16)

LCM = 219628863229440/32

LCM = 6863401975920

Thus, we can understand that the LCM of 980,842,618,626,688 is 6863401975920.
