Given numbers are 157,169,471,312
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,169,471,312 is 636792.
Find LCM of 157,169,471,312 with Prime Factorization
| 3 | 157, 169, 471, 312 |
| 13 | 157, 169, 157, 104 |
| 157 | 157, 13, 157, 8 |
| 1, 13, 1, 8 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 157 x 1 x 13 x 1 x 8 = 636792
Therefore, the lowest common multiple of 157,169,471,312 is 636792.
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.
157 x 169 x 471 x 312 = 3899077416
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.
157 : 1, 157
169 : 1, 13, 169
471 : 1, 3, 157, 471
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,169,471,312, is 1.
Now, the common factors can be found like this.
157:157
169:13x 13
471:3x 157
312:2x 2x 2x 3x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 13x 157 = 6123
Therefore, the value for common factors is 6123.
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 = 3899077416/(1x6123)
LCM = 3899077416/6123
LCM = 636792
Thus, we can understand that the LCM of 157,169,471,312 is 636792.
