Given numbers are 637,797,821,980,780

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

The LCM of 637,797,821,980,780 is 25008760140.

Find LCM of 637,797,821,980,780 with Prime Factorization

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

2 x 2 x 5 x 7 x 7 x 13 x 1 x 797 x 821 x 1 x 3 = 25008760140

Therefore, the lowest common multiple of 637,797,821,980,780 is 25008760140.

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.

637 x 797 x 821 x 980 x 780 = 318611604183600

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.

637 : 1, 7, 13, 49, 91, 637

797 : 1, 797

821 : 1, 821

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

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 637,797,821,980,780, is 1.

Now, the common factors can be found like this.

637:7x 7x 13

797:797

821:821

980:2x 2x 5x 7x 7

780:2x 2x 3x 5x 13

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 5x 7x 7x 13 = 12740

Therefore, the value for common factors is 12740.

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 = 318611604183600/(1x12740)

LCM = 318611604183600/12740

LCM = 25008760140

Thus, we can understand that the LCM of 637,797,821,980,780 is 25008760140.
