Find LCM of 772,198,105,671,553 with Prime Factorization
| 2 | 772, 198, 105, 671, 553 |
| 3 | 386, 99, 105, 671, 553 |
| 7 | 386, 33, 35, 671, 553 |
| 11 | 386, 33, 5, 671, 79 |
| 386, 3, 5, 61, 79 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 11 x 386 x 3 x 5 x 61 x 79 = 12890728620
Therefore, the lowest common multiple of 772,198,105,671,553 is 12890728620.
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.
772 x 198 x 105 x 671 x 553 = 5955516622440
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.
772 : 1, 2, 4, 193, 386, 772
198 : 1, 2, 3, 6, 9, 11, 18, 22, 33, 66, 99, 198
105 : 1, 3, 5, 7, 15, 21, 35, 105
671 : 1, 11, 61, 671
553 : 1, 7, 79, 553
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 772,198,105,671,553, is 1.
Now, the common factors can be found like this.
772:2x 2x 193
198:2x 3x 3x 11
105:3x 5x 7
671:11x 61
553:7x 79
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 7x 11 = 462
Therefore, the value for common factors is 462.
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 = 5955516622440/(1x462)
LCM = 5955516622440/462
LCM = 12890728620
Thus, we can understand that the LCM of 772,198,105,671,553 is 12890728620.
