Find LCM of 671,624,902,921,940 with Prime Factorization
| 2 | 671, 624, 902, 921, 940 |
| 2 | 671, 312, 451, 921, 470 |
| 3 | 671, 156, 451, 921, 235 |
| 11 | 671, 52, 451, 307, 235 |
| 61, 52, 41, 307, 235 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 61 x 52 x 41 x 307 x 235 = 1238503403280
Therefore, the lowest common multiple of 671,624,902,921,940 is 1238503403280.
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.
671 x 624 x 902 x 921 x 940 = 326964898465920
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.
671 : 1, 11, 61, 671
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
902 : 1, 2, 11, 22, 41, 82, 451, 902
921 : 1, 3, 307, 921
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,624,902,921,940, is 1.
Now, the common factors can be found like this.
671:11x 61
624:2x 2x 2x 2x 3x 13
902:2x 11x 41
921:3x 307
940:2x 2x 5x 47
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 2x 3x 11 = 264
Therefore, the value for common factors is 264.
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 = 326964898465920/(1x264)
LCM = 326964898465920/264
LCM = 1238503403280
Thus, we can understand that the LCM of 671,624,902,921,940 is 1238503403280.
