Find LCM of 647,431,374,476,968 with Prime Factorization
| 2 | 647, 431, 374, 476, 968 |
| 2 | 647, 431, 187, 238, 484 |
| 11 | 647, 431, 187, 119, 242 |
| 17 | 647, 431, 17, 119, 22 |
| 647, 431, 1, 7, 22 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 17 x 647 x 431 x 1 x 7 x 22 = 32122095544
Therefore, the lowest common multiple of 647,431,374,476,968 is 32122095544.
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.
647 x 431 x 374 x 476 x 968 = 48054654933824
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.
647 : 1, 647
431 : 1, 431
374 : 1, 2, 11, 17, 22, 34, 187, 374
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,431,374,476,968, is 1.
Now, the common factors can be found like this.
647:647
431:431
374:2x 11x 17
476:2x 2x 7x 17
968:2x 2x 2x 11x 11
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 11x 17 = 1496
Therefore, the value for common factors is 1496.
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 = 48054654933824/(1x1496)
LCM = 48054654933824/1496
LCM = 32122095544
Thus, we can understand that the LCM of 647,431,374,476,968 is 32122095544.
