Find LCM of 217,767,690,936,854 with Prime Factorization
| 2 | 217, 767, 690, 936, 854 |
| 3 | 217, 767, 345, 468, 427 |
| 7 | 217, 767, 115, 156, 427 |
| 13 | 31, 767, 115, 156, 61 |
| 31, 59, 115, 12, 61 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 13 x 31 x 59 x 115 x 12 x 61 = 84065010120
Therefore, the lowest common multiple of 217,767,690,936,854 is 84065010120.
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.
217 x 767 x 690 x 936 x 854 = 91798991051040
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.
217 : 1, 7, 31, 217
767 : 1, 13, 59, 767
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
936 : 1, 2, 3, 4, 6, 8, 9, 12, 13, 18, 24, 26, 36, 39, 52, 72, 78, 104, 117, 156, 234, 312, 468, 936
854 : 1, 2, 7, 14, 61, 122, 427, 854
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,767,690,936,854, is 1.
Now, the common factors can be found like this.
217:7x 31
767:13x 59
690:2x 3x 5x 23
936:2x 2x 2x 3x 3x 13
854:2x 7x 61
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 3x 7x 13 = 1092
Therefore, the value for common factors is 1092.
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 = 91798991051040/(1x1092)
LCM = 91798991051040/1092
LCM = 84065010120
Thus, we can understand that the LCM of 217,767,690,936,854 is 84065010120.
