The LCM of 456,968,968,690 is 6345240.
Find LCM of 456,968,968,690 with Prime Factorization
| 2 | 456, 968, 968, 690 |
| 2 | 228, 484, 484, 345 |
| 2 | 114, 242, 242, 345 |
| 3 | 57, 121, 121, 345 |
| 11 | 19, 121, 121, 115 |
| 11 | 19, 11, 11, 115 |
| 19, 1, 1, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 11 x 11 x 19 x 1 x 1 x 115 = 6345240
Therefore, the lowest common multiple of 456,968,968,690 is 6345240.
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.
456 x 968 x 968 x 690 = 294825231360
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.
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 456,968,968,690, is 2.
Now, the common factors can be found like this.
456:2x 2x 2x 3x 19
968:2x 2x 2x 11x 11
968:2x 2x 2x 11x 11
690:2x 3x 5x 23
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 2x 2x 3x 11x 11 = 23232
Therefore, the value for common factors is 23232.
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 = 294825231360/(2x23232)
LCM = 294825231360/46464
LCM = 6345240
Thus, we can understand that the LCM of 456,968,968,690 is 6345240.
