Find LCM of 642,755,568,880,710 with Prime Factorization
2 | 642, 755, 568, 880, 710 |
2 | 321, 755, 284, 440, 355 |
2 | 321, 755, 142, 220, 355 |
5 | 321, 755, 71, 110, 355 |
71 | 321, 151, 71, 22, 71 |
321, 151, 1, 22, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 71 x 321 x 151 x 1 x 22 x 1 = 3028468080
Therefore, the lowest common multiple of 642,755,568,880,710 is 3028468080.
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.
642 x 755 x 568 x 880 x 710 = 172016986944000
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.
642 : 1, 2, 3, 6, 107, 214, 321, 642
755 : 1, 5, 151, 755
568 : 1, 2, 4, 8, 71, 142, 284, 568
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
710 : 1, 2, 5, 10, 71, 142, 355, 710
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 642,755,568,880,710, is 1.
Now, the common factors can be found like this.
642:2x 3x 107
755:5x 151
568:2x 2x 2x 71
880:2x 2x 2x 2x 5x 11
710:2x 5x 71
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 2x 2x 5x 5x 71 = 56800
Therefore, the value for common factors is 56800.
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 = 172016986944000/(1x56800)
LCM = 172016986944000/56800
LCM = 3028468080
Thus, we can understand that the LCM of 642,755,568,880,710 is 3028468080.
