Given numbers are 947,132,820,164
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 947,132,820,164 is 25625820.
Find LCM of 947,132,820,164 with Prime Factorization
2 | 947, 132, 820, 164 |
2 | 947, 66, 410, 82 |
41 | 947, 33, 205, 41 |
947, 33, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 41 x 947 x 33 x 5 x 1 = 25625820
Therefore, the lowest common multiple of 947,132,820,164 is 25625820.
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.
947 x 132 x 820 x 164 = 16810537920
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.
947 : 1, 947
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
164 : 1, 2, 4, 41, 82, 164
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 947,132,820,164, is 1.
Now, the common factors can be found like this.
947:947
132:2x 2x 3x 11
820:2x 2x 5x 41
164:2x 2x 41
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 2x 2x 41 = 656
Therefore, the value for common factors is 656.
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 = 16810537920/(1x656)
LCM = 16810537920/656
LCM = 25625820
Thus, we can understand that the LCM of 947,132,820,164 is 25625820.
