Find LCM of 252,485,971,865,639 with Prime Factorization
| 3 | 252, 485, 971, 865, 639 |
| 3 | 84, 485, 971, 865, 213 |
| 5 | 28, 485, 971, 865, 71 |
| 28, 97, 971, 173, 71 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 28 x 97 x 971 x 173 x 71 = 1457692640460
Therefore, the lowest common multiple of 252,485,971,865,639 is 1457692640460.
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.
252 x 485 x 971 x 865 x 639 = 65596168820700
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.
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
485 : 1, 5, 97, 485
971 : 1, 971
865 : 1, 5, 173, 865
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 252,485,971,865,639, is 1.
Now, the common factors can be found like this.
252:2x 2x 3x 3x 7
485:5x 97
971:971
865:5x 173
639:3x 3x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5 = 45
Therefore, the value for common factors is 45.
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 = 65596168820700/(1x45)
LCM = 65596168820700/45
LCM = 1457692640460
Thus, we can understand that the LCM of 252,485,971,865,639 is 1457692640460.
