Given numbers are 772,789,549,456,979
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 772,789,549,456,979 is 4146786554328.
Find LCM of 772,789,549,456,979 with Prime Factorization
| 2 | 772, 789, 549, 456, 979 |
| 2 | 386, 789, 549, 228, 979 |
| 3 | 193, 789, 549, 114, 979 |
| 193, 263, 183, 38, 979 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 193 x 263 x 183 x 38 x 979 = 4146786554328
Therefore, the lowest common multiple of 772,789,549,456,979 is 4146786554328.
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.
772 x 789 x 549 x 456 x 979 = 149284315955808
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.
772 : 1, 2, 4, 193, 386, 772
789 : 1, 3, 263, 789
549 : 1, 3, 9, 61, 183, 549
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,789,549,456,979, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
789:3x 263
549:3x 3x 61
456:2x 2x 2x 3x 19
979:11x 89
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 3 = 36
Therefore, the value for common factors is 36.
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 = 149284315955808/(1x36)
LCM = 149284315955808/36
LCM = 4146786554328
Thus, we can understand that the LCM of 772,789,549,456,979 is 4146786554328.
