Given numbers are 665,698,157,698

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

The LCM of 665,698,157,698 is 72874690.

Find LCM of 665,698,157,698 with Prime Factorization

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

2 x 349 x 665 x 1 x 157 x 1 = 72874690

Therefore, the lowest common multiple of 665,698,157,698 is 72874690.

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.

665 x 698 x 157 x 698 = 50866533620

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.

665 : 1, 5, 7, 19, 35, 95, 133, 665

698 : 1, 2, 349, 698

157 : 1, 157

698 : 1, 2, 349, 698

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 665,698,157,698, is 1.

Now, the common factors can be found like this.

665:5x 7x 19

698:2x 349

157:157

698:2x 349

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 349 = 698

Therefore, the value for common factors is 698.

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 = 50866533620/(1x698)

LCM = 50866533620/698

LCM = 72874690

Thus, we can understand that the LCM of 665,698,157,698 is 72874690.
