Given numbers are 690,163,537,126

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

The LCM of 690,163,537,126 is 422774730.

Find LCM of 690,163,537,126 with Prime Factorization

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

2 x 3 x 115 x 163 x 179 x 21 = 422774730

Therefore, the lowest common multiple of 690,163,537,126 is 422774730.

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 163 x 537 x 126 = 7609945140

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

163 : 1, 163

537 : 1, 3, 179, 537

126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,163,537,126, is 1.

Now, the common factors can be found like this.

690:2x 3x 5x 23

163:163

537:3x 179

126:2x 3x 3x 7

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

2x 3x 3 = 18

Therefore, the value for common factors is 18.

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 = 7609945140/(1x18)

LCM = 7609945140/18

LCM = 422774730

Thus, we can understand that the LCM of 690,163,537,126 is 422774730.
