Find LCM of 980,910,983,572,840 with Prime Factorization
| 2 | 980, 910, 983, 572, 840 |
| 2 | 490, 455, 983, 286, 420 |
| 5 | 245, 455, 983, 143, 210 |
| 7 | 49, 91, 983, 143, 42 |
| 13 | 7, 13, 983, 143, 6 |
| 7, 1, 983, 11, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 13 x 7 x 1 x 983 x 11 x 6 = 826545720
Therefore, the lowest common multiple of 980,910,983,572,840 is 826545720.
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 910 x 983 x 572 x 840 = 421207698912000
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
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
983 : 1, 983
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,910,983,572,840, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
910:2x 5x 7x 13
983:983
572:2x 2x 11x 13
840:2x 2x 2x 3x 5x 7
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 7x 7x 13 = 509600
Therefore, the value for common factors is 509600.
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 = 421207698912000/(1x509600)
LCM = 421207698912000/509600
LCM = 826545720
Thus, we can understand that the LCM of 980,910,983,572,840 is 826545720.
