Find LCM of 689,938,735,876,123 with Prime Factorization
2 | 689, 938, 735, 876, 123 |
3 | 689, 469, 735, 438, 123 |
7 | 689, 469, 245, 146, 41 |
689, 67, 35, 146, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 689 x 67 x 35 x 146 x 41 = 406207625460
Therefore, the lowest common multiple of 689,938,735,876,123 is 406207625460.
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.
689 x 938 x 735 x 876 x 123 = 51182160807960
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.
689 : 1, 13, 53, 689
938 : 1, 2, 7, 14, 67, 134, 469, 938
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
876 : 1, 2, 3, 4, 6, 12, 73, 146, 219, 292, 438, 876
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 689,938,735,876,123, is 1.
Now, the common factors can be found like this.
689:13x 53
938:2x 7x 67
735:3x 5x 7x 7
876:2x 2x 3x 73
123:3x 41
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 7 = 126
Therefore, the value for common factors is 126.
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 = 51182160807960/(1x126)
LCM = 51182160807960/126
LCM = 406207625460
Thus, we can understand that the LCM of 689,938,735,876,123 is 406207625460.
