Find LCM of 693,657,120,456,454 with Prime Factorization
| 2 | 693, 657, 120, 456, 454 |
| 2 | 693, 657, 60, 228, 227 |
| 2 | 693, 657, 30, 114, 227 |
| 3 | 693, 657, 15, 57, 227 |
| 3 | 231, 219, 5, 19, 227 |
| 77, 73, 5, 19, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 77 x 73 x 5 x 19 x 227 = 8727614280
Therefore, the lowest common multiple of 693,657,120,456,454 is 8727614280.
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.
693 x 657 x 120 x 456 x 454 = 11310988106880
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.
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
657 : 1, 3, 9, 73, 219, 657
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
454 : 1, 2, 227, 454
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 693,657,120,456,454, is 1.
Now, the common factors can be found like this.
693:3x 3x 7x 11
657:3x 3x 73
120:2x 2x 2x 3x 5
456:2x 2x 2x 3x 19
454:2x 227
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 2x 3x 3x 3x 3 = 1296
Therefore, the value for common factors is 1296.
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 = 11310988106880/(1x1296)
LCM = 11310988106880/1296
LCM = 8727614280
Thus, we can understand that the LCM of 693,657,120,456,454 is 8727614280.
