Find LCM of 132,189,681,346,972 with Prime Factorization
2 | 132, 189, 681, 346, 972 |
2 | 66, 189, 681, 173, 486 |
3 | 33, 189, 681, 173, 243 |
3 | 11, 63, 227, 173, 81 |
3 | 11, 21, 227, 173, 27 |
11, 7, 227, 173, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 3 x 11 x 7 x 227 x 173 x 9 = 2939198724
Therefore, the lowest common multiple of 132,189,681,346,972 is 2939198724.
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.
132 x 189 x 681 x 346 x 972 = 5713802319456
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.
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
189 : 1, 3, 7, 9, 21, 27, 63, 189
681 : 1, 3, 227, 681
346 : 1, 2, 173, 346
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 132,189,681,346,972, is 1.
Now, the common factors can be found like this.
132:2x 2x 3x 11
189:3x 3x 3x 7
681:3x 227
346:2x 173
972:2x 2x 3x 3x 3x 3x 3
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 3x 3x 3x 3x 3 = 1944
Therefore, the value for common factors is 1944.
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 = 5713802319456/(1x1944)
LCM = 5713802319456/1944
LCM = 2939198724
Thus, we can understand that the LCM of 132,189,681,346,972 is 2939198724.
