Given numbers are 649,454,158,172

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

The LCM of 649,454,158,172 is 2001824924.

Find LCM of 649,454,158,172 with Prime Factorization

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

2 x 649 x 227 x 79 x 86 = 2001824924

Therefore, the lowest common multiple of 649,454,158,172 is 2001824924.

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.

649 x 454 x 158 x 172 = 8007299696

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.

649 : 1, 11, 59, 649

454 : 1, 2, 227, 454

158 : 1, 2, 79, 158

172 : 1, 2, 4, 43, 86, 172

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,454,158,172, is 1.

Now, the common factors can be found like this.

649:11x 59

454:2x 227

158:2x 79

172:2x 2x 43

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 = 8007299696/(1x4)

LCM = 8007299696/4

LCM = 2001824924

Thus, we can understand that the LCM of 649,454,158,172 is 2001824924.
