Find LCM of 495,971,442,897,690 with Prime Factorization
| 2 | 495, 971, 442, 897, 690 |
| 3 | 495, 971, 221, 897, 345 |
| 5 | 165, 971, 221, 299, 115 |
| 13 | 33, 971, 221, 299, 23 |
| 23 | 33, 971, 17, 23, 23 |
| 33, 971, 17, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 13 x 23 x 33 x 971 x 17 x 1 x 1 = 4886237070
Therefore, the lowest common multiple of 495,971,442,897,690 is 4886237070.
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.
495 x 971 x 442 x 897 x 690 = 131488639553700
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.
495 : 1, 3, 5, 9, 11, 15, 33, 45, 55, 99, 165, 495
971 : 1, 971
442 : 1, 2, 13, 17, 26, 34, 221, 442
897 : 1, 3, 13, 23, 39, 69, 299, 897
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 495,971,442,897,690, is 1.
Now, the common factors can be found like this.
495:3x 3x 5x 11
971:971
442:2x 13x 17
897:3x 13x 23
690:2x 3x 5x 23
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 5x 13x 23 = 26910
Therefore, the value for common factors is 26910.
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 = 131488639553700/(1x26910)
LCM = 131488639553700/26910
LCM = 4886237070
Thus, we can understand that the LCM of 495,971,442,897,690 is 4886237070.
