Given numbers are 735,153,646,856
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 735,153,646,856 is 609656040.
Find LCM of 735,153,646,856 with Prime Factorization
| 2 | 735, 153, 646, 856 |
| 3 | 735, 153, 323, 428 |
| 17 | 245, 51, 323, 428 |
| 245, 3, 19, 428 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 245 x 3 x 19 x 428 = 609656040
Therefore, the lowest common multiple of 735,153,646,856 is 609656040.
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.
735 x 153 x 646 x 856 = 62184916080
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.
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
153 : 1, 3, 9, 17, 51, 153
646 : 1, 2, 17, 19, 34, 38, 323, 646
856 : 1, 2, 4, 8, 107, 214, 428, 856
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 735,153,646,856, is 1.
Now, the common factors can be found like this.
735:3x 5x 7x 7
153:3x 3x 17
646:2x 17x 19
856:2x 2x 2x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 17 = 102
Therefore, the value for common factors is 102.
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 = 62184916080/(1x102)
LCM = 62184916080/102
LCM = 609656040
Thus, we can understand that the LCM of 735,153,646,856 is 609656040.
