Given numbers are 664,126,826,521,690

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

The LCM of 664,126,826,521,690 is 147875492520.

Find LCM of 664,126,826,521,690 with Prime Factorization

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

2 x 3 x 7 x 332 x 3 x 59 x 521 x 115 = 147875492520

Therefore, the lowest common multiple of 664,126,826,521,690 is 147875492520.

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.

664 x 126 x 826 x 521 x 690 = 24843082743360

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.

664 : 1, 2, 4, 8, 83, 166, 332, 664

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

826 : 1, 2, 7, 14, 59, 118, 413, 826

521 : 1, 521

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

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 664,126,826,521,690, is 1.

Now, the common factors can be found like this.

664:2x 2x 2x 83

126:2x 3x 3x 7

826:2x 7x 59

521:521

690:2x 3x 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.

2x 2x 2x 3x 7 = 168

Therefore, the value for common factors is 168.

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 = 24843082743360/(1x168)

LCM = 24843082743360/168

LCM = 147875492520

Thus, we can understand that the LCM of 664,126,826,521,690 is 147875492520.
