Given numbers are 667,451,424,742

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

The LCM of 667,451,424,742 is 892824856.

Find LCM of 667,451,424,742 with Prime Factorization

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

2 x 53 x 667 x 451 x 4 x 7 = 892824856

Therefore, the lowest common multiple of 667,451,424,742 is 892824856.

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.

667 x 451 x 424 x 742 = 94639434736

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.

667 : 1, 23, 29, 667

451 : 1, 11, 41, 451

424 : 1, 2, 4, 8, 53, 106, 212, 424

742 : 1, 2, 7, 14, 53, 106, 371, 742

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 667,451,424,742, is 1.

Now, the common factors can be found like this.

667:23x 29

451:11x 41

424:2x 2x 2x 53

742:2x 7x 53

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

2x 53 = 106

Therefore, the value for common factors is 106.

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 = 94639434736/(1x106)

LCM = 94639434736/106

LCM = 892824856

Thus, we can understand that the LCM of 667,451,424,742 is 892824856.
