Find LCM of 668,682,139,621,660 with Prime Factorization


2 668, 682, 139, 621, 660
2 334, 341, 139, 621, 330
3 167, 341, 139, 621, 165
11 167, 341, 139, 207, 55
167, 31, 139, 207, 5

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

2 x 2 x 3 x 11 x 167 x 31 x 139 x 207 x 5 = 98312161860

Therefore, the lowest common multiple of 668,682,139,621,660 is 98312161860.

LCM Formula to Find Lowest Common Multiple of 668,682,139,621,660

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.

668 x 682 x 139 x 621 x 660 = 25954410731040

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.

668 : 1, 2, 4, 167, 334, 668

682 : 1, 2, 11, 22, 31, 62, 341, 682

139 : 1, 139

621 : 1, 3, 9, 23, 27, 69, 207, 621

660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,682,139,621,660, is 1.

Now, the common factors can be found like this.

668:2x 2x 167

682:2x 11x 31

139:139

621:3x 3x 3x 23

660:2x 2x 3x 5x 11

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 2x 3x 11 = 264

Therefore, the value for common factors is 264.

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 = 25954410731040/(1x264)

LCM = 25954410731040/264

LCM = 98312161860

Thus, we can understand that the LCM of 668,682,139,621,660 is 98312161860.
