Given numbers are 942,690,131,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 942,690,131,178 is 1263019470.
Find LCM of 942,690,131,178 with Prime Factorization
| 2 | 942, 690, 131, 178 |
| 3 | 471, 345, 131, 89 |
| 157, 115, 131, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 157 x 115 x 131 x 89 = 1263019470
Therefore, the lowest common multiple of 942,690,131,178 is 1263019470.
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.
942 x 690 x 131 x 178 = 15156233640
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.
942 : 1, 2, 3, 6, 157, 314, 471, 942
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
131 : 1, 131
178 : 1, 2, 89, 178
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 942,690,131,178, is 1.
Now, the common factors can be found like this.
942:2x 3x 157
690:2x 3x 5x 23
131:131
178:2x 89
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 3 = 12
Therefore, the value for common factors is 12.
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 = 15156233640/(1x12)
LCM = 15156233640/12
LCM = 1263019470
Thus, we can understand that the LCM of 942,690,131,178 is 1263019470.
