Find LCM of 690,780,392,897,526 with Prime Factorization
2 | 690, 780, 392, 897, 526 |
2 | 345, 390, 196, 897, 263 |
3 | 345, 195, 98, 897, 263 |
5 | 115, 65, 98, 299, 263 |
13 | 23, 13, 98, 299, 263 |
23 | 23, 1, 98, 23, 263 |
1, 1, 98, 1, 263 |
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 1 x 98 x 1 x 263 = 462385560
Therefore, the lowest common multiple of 690,780,392,897,526 is 462385560.
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 392 x 897 x 526 = 99542363356800
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
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
897 : 1, 3, 13, 23, 39, 69, 299, 897
526 : 1, 2, 263, 526
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 690,780,392,897,526, is 1.
Now, the common factors can be found like this.
690:2x 3x 5x 23
780:2x 2x 3x 5x 13
392:2x 2x 2x 7x 7
897:3x 13x 23
526:2x 263
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 3x 3x 5x 13x 23 = 215280
Therefore, the value for common factors is 215280.
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 = 99542363356800/(1x215280)
LCM = 99542363356800/215280
LCM = 462385560
Thus, we can understand that the LCM of 690,780,392,897,526 is 462385560.
