Given numbers are 922,987,761,451,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 922,987,761,451,840 is 6246536299080.
Find LCM of 922,987,761,451,840 with Prime Factorization
| 2 | 922, 987, 761, 451, 840 |
| 3 | 461, 987, 761, 451, 420 |
| 7 | 461, 329, 761, 451, 140 |
| 461, 47, 761, 451, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 461 x 47 x 761 x 451 x 20 = 6246536299080
Therefore, the lowest common multiple of 922,987,761,451,840 is 6246536299080.
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.
922 x 987 x 761 x 451 x 840 = 262354524561360
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.
922 : 1, 2, 461, 922
987 : 1, 3, 7, 21, 47, 141, 329, 987
761 : 1, 761
451 : 1, 11, 41, 451
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 922,987,761,451,840, is 1.
Now, the common factors can be found like this.
922:2x 461
987:3x 7x 47
761:761
451:11x 41
840:2x 2x 2x 3x 5x 7
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 7 = 42
Therefore, the value for common factors is 42.
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 = 262354524561360/(1x42)
LCM = 262354524561360/42
LCM = 6246536299080
Thus, we can understand that the LCM of 922,987,761,451,840 is 6246536299080.
