Find LCM of 980,682,770,242,884 with Prime Factorization
| 2 | 980, 682, 770, 242, 884 |
| 2 | 490, 341, 385, 121, 442 |
| 5 | 245, 341, 385, 121, 221 |
| 7 | 49, 341, 77, 121, 221 |
| 11 | 7, 341, 11, 121, 221 |
| 7, 31, 1, 11, 221 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 11 x 7 x 31 x 1 x 11 x 221 = 812391580
Therefore, the lowest common multiple of 980,682,770,242,884 is 812391580.
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 682 x 770 x 242 x 884 = 110095306921600
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
682 : 1, 2, 11, 22, 31, 62, 341, 682
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
242 : 1, 2, 11, 22, 121, 242
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,682,770,242,884, is 2.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
682:2x 11x 31
770:2x 5x 7x 11
242:2x 11x 11
884:2x 2x 13x 17
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 5x 7x 11x 11 = 67760
Therefore, the value for common factors is 67760.
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 = 110095306921600/(2x67760)
LCM = 110095306921600/135520
LCM = 812391580
Thus, we can understand that the LCM of 980,682,770,242,884 is 812391580.
