Find LCM of 980,920,219,448,779 with Prime Factorization
| 2 | 980, 920, 219, 448, 779 |
| 2 | 490, 460, 219, 224, 779 |
| 2 | 245, 230, 219, 112, 779 |
| 5 | 245, 115, 219, 56, 779 |
| 7 | 49, 23, 219, 56, 779 |
| 7, 23, 219, 8, 779 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 7 x 23 x 219 x 8 x 779 = 61525544640
Therefore, the lowest common multiple of 980,920,219,448,779 is 61525544640.
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.
980 x 920 x 219 x 448 x 779 = 68908609996800
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
219 : 1, 3, 73, 219
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,920,219,448,779, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
920:2x 2x 2x 5x 23
219:3x 73
448:2x 2x 2x 2x 2x 2x 7
779:19x 41
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 7 = 1120
Therefore, the value for common factors is 1120.
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 = 68908609996800/(1x1120)
LCM = 68908609996800/1120
LCM = 61525544640
Thus, we can understand that the LCM of 980,920,219,448,779 is 61525544640.
