Given numbers are 847,278,661,712,774

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

The LCM of 847,278,661,712,774 is 21443250978072.

Find LCM of 847,278,661,712,774 with Prime Factorization

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

2 x 847 x 139 x 661 x 356 x 387 = 21443250978072

Therefore, the lowest common multiple of 847,278,661,712,774 is 21443250978072.

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.

847 x 278 x 661 x 712 x 774 = 85773003912288

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.

847 : 1, 7, 11, 77, 121, 847

278 : 1, 2, 139, 278

661 : 1, 661

712 : 1, 2, 4, 8, 89, 178, 356, 712

774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 847,278,661,712,774, is 1.

Now, the common factors can be found like this.

847:7x 11x 11

278:2x 139

661:661

712:2x 2x 2x 89

774:2x 3x 3x 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 = 85773003912288/(1x4)

LCM = 85773003912288/4

LCM = 21443250978072

Thus, we can understand that the LCM of 847,278,661,712,774 is 21443250978072.
