Given numbers are 698,788,990,553

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

The LCM of 698,788,990,553 is 75280409820.

Find LCM of 698,788,990,553 with Prime Factorization

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

2 x 349 x 394 x 495 x 553 = 75280409820

Therefore, the lowest common multiple of 698,788,990,553 is 75280409820.

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 788 x 990 x 553 = 301121639280

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

788 : 1, 2, 4, 197, 394, 788

990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990

553 : 1, 7, 79, 553

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,788,990,553, is 1.

Now, the common factors can be found like this.

698:2x 349

788:2x 2x 197

990:2x 3x 3x 5x 11

553:7x 79

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 = 301121639280/(1x4)

LCM = 301121639280/4

LCM = 75280409820

Thus, we can understand that the LCM of 698,788,990,553 is 75280409820.
