Given numbers are 868,451,126,454

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

The LCM of 868,451,126,454 is 799769124.

Find LCM of 868,451,126,454 with Prime Factorization

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

2 x 7 x 62 x 451 x 9 x 227 = 799769124

Therefore, the lowest common multiple of 868,451,126,454 is 799769124.

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.

868 x 451 x 126 x 454 = 22393535472

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.

868 : 1, 2, 4, 7, 14, 28, 31, 62, 124, 217, 434, 868

451 : 1, 11, 41, 451

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

454 : 1, 2, 227, 454

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 868,451,126,454, is 1.

Now, the common factors can be found like this.

868:2x 2x 7x 31

451:11x 41

126:2x 3x 3x 7

454:2x 227

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 7 = 28

Therefore, the value for common factors is 28.

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 = 22393535472/(1x28)

LCM = 22393535472/28

LCM = 799769124

Thus, we can understand that the LCM of 868,451,126,454 is 799769124.
