Given numbers are 407,974,985,854

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

The LCM of 407,974,985,854 is 166731428710.

Find LCM of 407,974,985,854 with Prime Factorization

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

2 x 407 x 487 x 985 x 427 = 166731428710

Therefore, the lowest common multiple of 407,974,985,854 is 166731428710.

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.

407 x 974 x 985 x 854 = 333462857420

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.

407 : 1, 11, 37, 407

974 : 1, 2, 487, 974

985 : 1, 5, 197, 985

854 : 1, 2, 7, 14, 61, 122, 427, 854

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 407,974,985,854, is 1.

Now, the common factors can be found like this.

407:11x 37

974:2x 487

985:5x 197

854:2x 7x 61

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

2 = 2

Therefore, the value for common factors is 2.

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 = 333462857420/(1x2)

LCM = 333462857420/2

LCM = 166731428710

Thus, we can understand that the LCM of 407,974,985,854 is 166731428710.
