Find LCM of 620,381,127,865,398 with Prime Factorization
| 2 | 620, 381, 127, 865, 398 |
| 5 | 310, 381, 127, 865, 199 |
| 127 | 62, 381, 127, 173, 199 |
| 62, 3, 1, 173, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 127 x 62 x 3 x 1 x 173 x 199 = 8132345940
Therefore, the lowest common multiple of 620,381,127,865,398 is 8132345940.
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.
620 x 381 x 127 x 865 x 398 = 10328079343800
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.
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
381 : 1, 3, 127, 381
127 : 1, 127
865 : 1, 5, 173, 865
398 : 1, 2, 199, 398
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 620,381,127,865,398, is 1.
Now, the common factors can be found like this.
620:2x 2x 5x 31
381:3x 127
127:127
865:5x 173
398:2x 199
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 127 = 1270
Therefore, the value for common factors is 1270.
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 = 10328079343800/(1x1270)
LCM = 10328079343800/1270
LCM = 8132345940
Thus, we can understand that the LCM of 620,381,127,865,398 is 8132345940.
