Given numbers are 478,771,938,938,669
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 478,771,938,938,669 is 38544283806.
Find LCM of 478,771,938,938,669 with Prime Factorization
| 2 | 478, 771, 938, 938, 669 |
| 3 | 239, 771, 469, 469, 669 |
| 7 | 239, 257, 469, 469, 223 |
| 67 | 239, 257, 67, 67, 223 |
| 239, 257, 1, 1, 223 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 67 x 239 x 257 x 1 x 1 x 223 = 38544283806
Therefore, the lowest common multiple of 478,771,938,938,669 is 38544283806.
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.
478 x 771 x 938 x 938 x 669 = 216927229260168
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.
478 : 1, 2, 239, 478
771 : 1, 3, 257, 771
938 : 1, 2, 7, 14, 67, 134, 469, 938
938 : 1, 2, 7, 14, 67, 134, 469, 938
669 : 1, 3, 223, 669
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 478,771,938,938,669, is 1.
Now, the common factors can be found like this.
478:2x 239
771:3x 257
938:2x 7x 67
938:2x 7x 67
669:3x 223
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 67 = 5628
Therefore, the value for common factors is 5628.
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 = 216927229260168/(1x5628)
LCM = 216927229260168/5628
LCM = 38544283806
Thus, we can understand that the LCM of 478,771,938,938,669 is 38544283806.
