Given numbers are 692,702,753,720
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 692,702,753,720 is 1219317840.
Find LCM of 692,702,753,720 with Prime Factorization
| 2 | 692, 702, 753, 720 |
| 2 | 346, 351, 753, 360 |
| 3 | 173, 351, 753, 180 |
| 3 | 173, 117, 251, 60 |
| 173, 39, 251, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 173 x 39 x 251 x 20 = 1219317840
Therefore, the lowest common multiple of 692,702,753,720 is 1219317840.
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.
692 x 702 x 753 x 720 = 263372653440
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.
692 : 1, 2, 4, 173, 346, 692
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
753 : 1, 3, 251, 753
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 692,702,753,720, is 1.
Now, the common factors can be found like this.
692:2x 2x 173
702:2x 3x 3x 3x 13
753:3x 251
720:2x 2x 2x 2x 3x 3x 5
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 3x 3x 3 = 216
Therefore, the value for common factors is 216.
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 = 263372653440/(1x216)
LCM = 263372653440/216
LCM = 1219317840
Thus, we can understand that the LCM of 692,702,753,720 is 1219317840.
