Find LCM of 972,177,122,549,745 with Prime Factorization
| 2 | 972, 177, 122, 549, 745 |
| 3 | 486, 177, 61, 549, 745 |
| 3 | 162, 59, 61, 183, 745 |
| 61 | 54, 59, 61, 61, 745 |
| 54, 59, 1, 1, 745 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 61 x 54 x 59 x 1 x 1 x 745 = 2606179860
Therefore, the lowest common multiple of 972,177,122,549,745 is 2606179860.
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 177 x 122 x 549 x 745 = 8584756458840
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
177 : 1, 3, 59, 177
122 : 1, 2, 61, 122
549 : 1, 3, 9, 61, 183, 549
745 : 1, 5, 149, 745
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,177,122,549,745, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
177:3x 59
122:2x 61
549:3x 3x 61
745:5x 149
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 61 = 3294
Therefore, the value for common factors is 3294.
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 = 8584756458840/(1x3294)
LCM = 8584756458840/3294
LCM = 2606179860
Thus, we can understand that the LCM of 972,177,122,549,745 is 2606179860.
