Given numbers are 142,689,157,157
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,689,157,157 is 15360566.
Find LCM of 142,689,157,157 with Prime Factorization
| 157 | 142, 689, 157, 157 |
| 142, 689, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
157 x 142 x 689 x 1 x 1 = 15360566
Therefore, the lowest common multiple of 142,689,157,157 is 15360566.
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.
142 x 689 x 157 x 157 = 2411608862
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.
142 : 1, 2, 71, 142
689 : 1, 13, 53, 689
157 : 1, 157
157 : 1, 157
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,689,157,157, is 1.
Now, the common factors can be found like this.
142:2x 71
689:13x 53
157:157
157:157
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
157 = 157
Therefore, the value for common factors is 157.
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 = 2411608862/(1x157)
LCM = 2411608862/157
LCM = 15360566
Thus, we can understand that the LCM of 142,689,157,157 is 15360566.
