Given numbers are 770,253,852,916,457
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,253,852,916,457 is 789550372380.
Find LCM of 770,253,852,916,457 with Prime Factorization
| 2 | 770, 253, 852, 916, 457 |
| 2 | 385, 253, 426, 458, 457 |
| 11 | 385, 253, 213, 229, 457 |
| 35, 23, 213, 229, 457 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 35 x 23 x 213 x 229 x 457 = 789550372380
Therefore, the lowest common multiple of 770,253,852,916,457 is 789550372380.
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.
770 x 253 x 852 x 916 x 457 = 69480432769440
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
253 : 1, 11, 23, 253
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
916 : 1, 2, 4, 229, 458, 916
457 : 1, 457
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,253,852,916,457, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
253:11x 23
852:2x 2x 3x 71
916:2x 2x 229
457:457
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 11 = 88
Therefore, the value for common factors is 88.
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 = 69480432769440/(1x88)
LCM = 69480432769440/88
LCM = 789550372380
Thus, we can understand that the LCM of 770,253,852,916,457 is 789550372380.
