Given numbers are 720,813,889,628,262
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 720,813,889,628,262 is 3567586372560.
Find LCM of 720,813,889,628,262 with Prime Factorization
| 2 | 720, 813, 889, 628, 262 |
| 2 | 360, 813, 889, 314, 131 |
| 3 | 180, 813, 889, 157, 131 |
| 60, 271, 889, 157, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 60 x 271 x 889 x 157 x 131 = 3567586372560
Therefore, the lowest common multiple of 720,813,889,628,262 is 3567586372560.
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.
720 x 813 x 889 x 628 x 262 = 85622072941440
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.
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
813 : 1, 3, 271, 813
889 : 1, 7, 127, 889
628 : 1, 2, 4, 157, 314, 628
262 : 1, 2, 131, 262
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 720,813,889,628,262, is 1.
Now, the common factors can be found like this.
720:2x 2x 2x 2x 3x 3x 5
813:3x 271
889:7x 127
628:2x 2x 157
262:2x 131
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 3 = 24
Therefore, the value for common factors is 24.
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 = 85622072941440/(1x24)
LCM = 85622072941440/24
LCM = 3567586372560
Thus, we can understand that the LCM of 720,813,889,628,262 is 3567586372560.
