The LCM of 979,588,640,570 is 1749982080.
Find LCM of 979,588,640,570 with Prime Factorization
| 2 | 979, 588, 640, 570 |
| 2 | 979, 294, 320, 285 |
| 3 | 979, 147, 160, 285 |
| 5 | 979, 49, 160, 95 |
| 979, 49, 32, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 979 x 49 x 32 x 19 = 1749982080
Therefore, the lowest common multiple of 979,588,640,570 is 1749982080.
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.
979 x 588 x 640 x 570 = 209997849600
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.
979 : 1, 11, 89, 979
588 : 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 49, 84, 98, 147, 196, 294, 588
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,588,640,570, is 1.
Now, the common factors can be found like this.
979:11x 89
588:2x 2x 3x 7x 7
640:2x 2x 2x 2x 2x 2x 2x 5
570:2x 3x 5x 19
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 5 = 120
Therefore, the value for common factors is 120.
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 = 209997849600/(1x120)
LCM = 209997849600/120
LCM = 1749982080
Thus, we can understand that the LCM of 979,588,640,570 is 1749982080.
