Given numbers are 157,178,137,990
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 157,178,137,990 is 1895157990.
Find LCM of 157,178,137,990 with Prime Factorization
2 | 157, 178, 137, 990 |
157, 89, 137, 495 |
Multiply the prime numbers at the bottom and the left side.
2 x 157 x 89 x 137 x 495 = 1895157990
Therefore, the lowest common multiple of 157,178,137,990 is 1895157990.
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 178 x 137 x 990 = 3790315980
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
178 : 1, 2, 89, 178
137 : 1, 137
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 157,178,137,990, is 1.
Now, the common factors can be found like this.
157:157
178:2x 89
137:137
990:2x 3x 3x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 3790315980/(1x2)
LCM = 3790315980/2
LCM = 1895157990
Thus, we can understand that the LCM of 157,178,137,990 is 1895157990.
