Given numbers are 151,616,308,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 151,616,308,931 is 12371128.
Find LCM of 151,616,308,931 with Prime Factorization
2 | 151, 616, 308, 931 |
2 | 151, 308, 154, 931 |
7 | 151, 77, 154, 931 |
11 | 151, 11, 22, 133 |
151, 1, 2, 133 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 11 x 151 x 1 x 2 x 133 = 12371128
Therefore, the lowest common multiple of 151,616,308,931 is 12371128.
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.
151 x 616 x 308 x 931 = 26672151968
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.
151 : 1, 151
616 : 1, 2, 4, 7, 8, 11, 14, 22, 28, 44, 56, 77, 88, 154, 308, 616
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 151,616,308,931, is 1.
Now, the common factors can be found like this.
151:151
616:2x 2x 2x 7x 11
308:2x 2x 7x 11
931:7x 7x 19
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 7x 7x 11 = 2156
Therefore, the value for common factors is 2156.
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 = 26672151968/(1x2156)
LCM = 26672151968/2156
LCM = 12371128
Thus, we can understand that the LCM of 151,616,308,931 is 12371128.
