Find LCM of 888,461,420,721,355 with Prime Factorization
| 2 | 888, 461, 420, 721, 355 |
| 2 | 444, 461, 210, 721, 355 |
| 3 | 222, 461, 105, 721, 355 |
| 5 | 74, 461, 35, 721, 355 |
| 7 | 74, 461, 7, 721, 71 |
| 74, 461, 1, 103, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 74 x 461 x 1 x 103 x 71 = 104779786440
Therefore, the lowest common multiple of 888,461,420,721,355 is 104779786440.
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.
888 x 461 x 420 x 721 x 355 = 44007510304800
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.
888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888
461 : 1, 461
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
721 : 1, 7, 103, 721
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,461,420,721,355, is 1.
Now, the common factors can be found like this.
888:2x 2x 2x 3x 37
461:461
420:2x 2x 3x 5x 7
721:7x 103
355:5x 71
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 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 44007510304800/(1x420)
LCM = 44007510304800/420
LCM = 104779786440
Thus, we can understand that the LCM of 888,461,420,721,355 is 104779786440.
