Given numbers are 698,988,119,494,780

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

The LCM of 698,988,119,494,780 is 615489420.

Find LCM of 698,988,119,494,780 with Prime Factorization

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

2 x 2 x 13 x 19 x 349 x 1 x 119 x 1 x 15 = 615489420

Therefore, the lowest common multiple of 698,988,119,494,780 is 615489420.

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.

698 x 988 x 119 x 494 x 780 = 31621384441920

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.

698 : 1, 2, 349, 698

988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988

119 : 1, 7, 17, 119

494 : 1, 2, 13, 19, 26, 38, 247, 494

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 698,988,119,494,780, is 1.

Now, the common factors can be found like this.

698:2x 349

988:2x 2x 13x 19

119:7x 17

494:2x 13x 19

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 2x 2x 13x 13x 19 = 51376

Therefore, the value for common factors is 51376.

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 = 31621384441920/(1x51376)

LCM = 31621384441920/51376

LCM = 615489420

Thus, we can understand that the LCM of 698,988,119,494,780 is 615489420.
