Find LCM of 702,901,639,756 with Prime Factorization
| 2 | 702, 901, 639, 756 |
| 3 | 351, 901, 639, 378 |
| 3 | 117, 901, 213, 126 |
| 3 | 39, 901, 71, 42 |
| 13, 901, 71, 14 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 3 x 13 x 901 x 71 x 14 = 628706988
Therefore, the lowest common multiple of 702,901,639,756 is 628706988.
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.
702 x 901 x 639 x 756 = 305551596168
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.
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
901 : 1, 17, 53, 901
639 : 1, 3, 9, 71, 213, 639
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 702,901,639,756, is 1.
Now, the common factors can be found like this.
702:2x 3x 3x 3x 13
901:17x 53
639:3x 3x 71
756:2x 2x 3x 3x 3x 7
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 3x 3 = 486
Therefore, the value for common factors is 486.
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 = 305551596168/(1x486)
LCM = 305551596168/486
LCM = 628706988
Thus, we can understand that the LCM of 702,901,639,756 is 628706988.
