Find LCM of 980,520,392,418,760 with Prime Factorization
| 2 | 980, 520, 392, 418, 760 |
| 2 | 490, 260, 196, 209, 380 |
| 2 | 245, 130, 98, 209, 190 |
| 5 | 245, 65, 49, 209, 95 |
| 7 | 49, 13, 49, 209, 19 |
| 7 | 7, 13, 7, 209, 19 |
| 19 | 1, 13, 1, 209, 19 |
| 1, 13, 1, 11, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 7 x 19 x 1 x 13 x 1 x 11 x 1 = 5325320
Therefore, the lowest common multiple of 980,520,392,418,760 is 5325320.
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 520 x 392 x 418 x 760 = 63460773376000
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
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
418 : 1, 2, 11, 19, 22, 38, 209, 418
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,520,392,418,760, is 2.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
520:2x 2x 2x 5x 13
392:2x 2x 2x 7x 7
418:2x 11x 19
760:2x 2x 2x 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 2x 2x 2x 2x 2x 5x 5x 7x 7x 19 = 5958400
Therefore, the value for common factors is 5958400.
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 = 63460773376000/(2x5958400)
LCM = 63460773376000/11916800
LCM = 5325320
Thus, we can understand that the LCM of 980,520,392,418,760 is 5325320.
