Given numbers are 615,156,141,611,474
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,156,141,611,474 is 118741740.
Find LCM of 615,156,141,611,474 with Prime Factorization
| 2 | 615, 156, 141, 611, 474 |
| 3 | 615, 78, 141, 611, 237 |
| 13 | 205, 26, 47, 611, 79 |
| 47 | 205, 2, 47, 47, 79 |
| 205, 2, 1, 1, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 47 x 205 x 2 x 1 x 1 x 79 = 118741740
Therefore, the lowest common multiple of 615,156,141,611,474 is 118741740.
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.
615 x 156 x 141 x 611 x 474 = 3917764969560
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
141 : 1, 3, 47, 141
611 : 1, 13, 47, 611
474 : 1, 2, 3, 6, 79, 158, 237, 474
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,156,141,611,474, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
156:2x 2x 3x 13
141:3x 47
611:13x 47
474:2x 3x 79
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 3x 3x 13x 47 = 32994
Therefore, the value for common factors is 32994.
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 = 3917764969560/(1x32994)
LCM = 3917764969560/32994
LCM = 118741740
Thus, we can understand that the LCM of 615,156,141,611,474 is 118741740.
