Find LCM of 651,748,623,968,397 with Prime Factorization
| 2 | 651, 748, 623, 968, 397 |
| 2 | 651, 374, 623, 484, 397 |
| 7 | 651, 187, 623, 242, 397 |
| 11 | 93, 187, 89, 242, 397 |
| 93, 17, 89, 22, 397 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 93 x 17 x 89 x 22 x 397 = 378517341048
Therefore, the lowest common multiple of 651,748,623,968,397 is 378517341048.
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.
651 x 748 x 623 x 968 x 397 = 116583341042784
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.
651 : 1, 3, 7, 21, 31, 93, 217, 651
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
623 : 1, 7, 89, 623
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
397 : 1, 397
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,748,623,968,397, is 1.
Now, the common factors can be found like this.
651:3x 7x 31
748:2x 2x 11x 17
623:7x 89
968:2x 2x 2x 11x 11
397:397
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 7x 11 = 308
Therefore, the value for common factors is 308.
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 = 116583341042784/(1x308)
LCM = 116583341042784/308
LCM = 378517341048
Thus, we can understand that the LCM of 651,748,623,968,397 is 378517341048.
