Find LCM of 972,556,132,767,121 with Prime Factorization
| 2 | 972, 556, 132, 767, 121 |
| 2 | 486, 278, 66, 767, 121 |
| 3 | 243, 139, 33, 767, 121 |
| 11 | 81, 139, 11, 767, 121 |
| 81, 139, 1, 767, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 81 x 139 x 1 x 767 x 11 = 12538968156
Therefore, the lowest common multiple of 972,556,132,767,121 is 12538968156.
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.
972 x 556 x 132 x 767 x 121 = 6620575186368
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
556 : 1, 2, 4, 139, 278, 556
132 : 1, 2, 3, 4, 6, 11, 12, 22, 33, 44, 66, 132
767 : 1, 13, 59, 767
121 : 1, 11, 121
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,556,132,767,121, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
556:2x 2x 139
132:2x 2x 3x 11
767:13x 59
121:11x 11
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 11 = 528
Therefore, the value for common factors is 528.
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 = 6620575186368/(1x528)
LCM = 6620575186368/528
LCM = 12538968156
Thus, we can understand that the LCM of 972,556,132,767,121 is 12538968156.
