Find LCM of 126,161,668,722,972 with Prime Factorization
2 | 126, 161, 668, 722, 972 |
2 | 63, 161, 334, 361, 486 |
3 | 63, 161, 167, 361, 243 |
3 | 21, 161, 167, 361, 81 |
7 | 7, 161, 167, 361, 27 |
1, 23, 167, 361, 27 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 1 x 23 x 167 x 361 x 27 = 9434433204
Therefore, the lowest common multiple of 126,161,668,722,972 is 9434433204.
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.
126 x 161 x 668 x 722 x 972 = 9509908669632
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.
126 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
161 : 1, 7, 23, 161
668 : 1, 2, 4, 167, 334, 668
722 : 1, 2, 19, 38, 361, 722
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 126,161,668,722,972, is 1.
Now, the common factors can be found like this.
126:2x 3x 3x 7
161:7x 23
668:2x 2x 167
722:2x 19x 19
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 2x 3x 3x 7 = 1008
Therefore, the value for common factors is 1008.
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 = 9509908669632/(1x1008)
LCM = 9509908669632/1008
LCM = 9434433204
Thus, we can understand that the LCM of 126,161,668,722,972 is 9434433204.
