Find LCM of 902,507,690,517,905 with Prime Factorization
2 | 902, 507, 690, 517, 905 |
3 | 451, 507, 345, 517, 905 |
5 | 451, 169, 115, 517, 905 |
11 | 451, 169, 23, 517, 181 |
41, 169, 23, 47, 181 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 41 x 169 x 23 x 47 x 181 = 447392572770
Therefore, the lowest common multiple of 902,507,690,517,905 is 447392572770.
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.
902 x 507 x 690 x 517 x 905 = 147639549014100
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.
902 : 1, 2, 11, 22, 41, 82, 451, 902
507 : 1, 3, 13, 39, 169, 507
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
517 : 1, 11, 47, 517
905 : 1, 5, 181, 905
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 902,507,690,517,905, is 1.
Now, the common factors can be found like this.
902:2x 11x 41
507:3x 13x 13
690:2x 3x 5x 23
517:11x 47
905:5x 181
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 11 = 330
Therefore, the value for common factors is 330.
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 = 147639549014100/(1x330)
LCM = 147639549014100/330
LCM = 447392572770
Thus, we can understand that the LCM of 902,507,690,517,905 is 447392572770.
