Find LCM of 355,408,639,909,494 with Prime Factorization
2 | 355, 408, 639, 909, 494 |
3 | 355, 204, 639, 909, 247 |
3 | 355, 68, 213, 303, 247 |
71 | 355, 68, 71, 101, 247 |
5, 68, 1, 101, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 71 x 5 x 68 x 1 x 101 x 247 = 10839970440
Therefore, the lowest common multiple of 355,408,639,909,494 is 10839970440.
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.
355 x 408 x 639 x 909 x 494 = 41560446666960
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.
355 : 1, 5, 71, 355
408 : 1, 2, 3, 4, 6, 8, 12, 17, 24, 34, 51, 68, 102, 136, 204, 408
639 : 1, 3, 9, 71, 213, 639
909 : 1, 3, 9, 101, 303, 909
494 : 1, 2, 13, 19, 26, 38, 247, 494
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 355,408,639,909,494, is 1.
Now, the common factors can be found like this.
355:5x 71
408:2x 2x 2x 3x 17
639:3x 3x 71
909:3x 3x 101
494:2x 13x 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 3x 3x 3x 71 = 3834
Therefore, the value for common factors is 3834.
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 = 41560446666960/(1x3834)
LCM = 41560446666960/3834
LCM = 10839970440
Thus, we can understand that the LCM of 355,408,639,909,494 is 10839970440.
