Find LCM of 690,780,925,572,136 with Prime Factorization
| 2 | 690, 780, 925, 572, 136 |
| 2 | 345, 390, 925, 286, 68 |
| 3 | 345, 195, 925, 143, 34 |
| 5 | 115, 65, 925, 143, 34 |
| 13 | 23, 13, 185, 143, 34 |
| 23, 1, 185, 11, 34 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 23 x 1 x 185 x 11 x 34 = 1241268600
Therefore, the lowest common multiple of 690,780,925,572,136 is 1241268600.
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.
690 x 780 x 925 x 572 x 136 = 38727580320000
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.
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
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
925 : 1, 5, 25, 37, 185, 925
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
136 : 1, 2, 4, 8, 17, 34, 68, 136
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,780,925,572,136, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
780:2x 2x 3x 5x 13
925:5x 5x 37
572:2x 2x 11x 13
136:2x 2x 2x 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 2x 3x 5x 5x 13 = 31200
Therefore, the value for common factors is 31200.
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 = 38727580320000/(1x31200)
LCM = 38727580320000/31200
LCM = 1241268600
Thus, we can understand that the LCM of 690,780,925,572,136 is 1241268600.
