Find LCM of 970,813,780,436,349 with Prime Factorization
2 | 970, 813, 780, 436, 349 |
2 | 485, 813, 390, 218, 349 |
3 | 485, 813, 195, 109, 349 |
5 | 485, 271, 65, 109, 349 |
97, 271, 13, 109, 349 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 97 x 271 x 13 x 109 x 349 = 779987338260
Therefore, the lowest common multiple of 970,813,780,436,349 is 779987338260.
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.
970 x 813 x 780 x 436 x 349 = 93598480591200
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.
970 : 1, 2, 5, 10, 97, 194, 485, 970
813 : 1, 3, 271, 813
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
436 : 1, 2, 4, 109, 218, 436
349 : 1, 349
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 970,813,780,436,349, is 1.
Now, the common factors can be found like this.
970:2x 5x 97
813:3x 271
780:2x 2x 3x 5x 13
436:2x 2x 109
349:349
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 = 93598480591200/(1x120)
LCM = 93598480591200/120
LCM = 779987338260
Thus, we can understand that the LCM of 970,813,780,436,349 is 779987338260.
