Given numbers are 690,815,127,575

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

The LCM of 690,815,127,575 is 71418450.

Find LCM of 690,815,127,575 with Prime Factorization

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

5 x 23 x 6 x 163 x 127 x 5 = 71418450

Therefore, the lowest common multiple of 690,815,127,575 is 71418450.

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.

690 x 815 x 127 x 575 = 41065608750

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.

690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690

815 : 1, 5, 163, 815

127 : 1, 127

575 : 1, 5, 23, 25, 115, 575

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,815,127,575, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

815:5x 163

127:127

575:5x 5x 23

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

5x 5x 23 = 575

Therefore, the value for common factors is 575.

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 = 41065608750/(1x575)

LCM = 41065608750/575

LCM = 71418450

Thus, we can understand that the LCM of 690,815,127,575 is 71418450.
