Find LCM of 520,954,765,962,221 with Prime Factorization
| 2 | 520, 954, 765, 962, 221 |
| 3 | 260, 477, 765, 481, 221 |
| 3 | 260, 159, 255, 481, 221 |
| 5 | 260, 53, 85, 481, 221 |
| 13 | 52, 53, 17, 481, 221 |
| 17 | 4, 53, 17, 37, 17 |
| 4, 53, 1, 37, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 17 x 4 x 53 x 1 x 37 x 1 = 156017160
Therefore, the lowest common multiple of 520,954,765,962,221 is 156017160.
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.
520 x 954 x 765 x 962 x 221 = 80682714122400
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
954 : 1, 2, 3, 6, 9, 18, 53, 106, 159, 318, 477, 954
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
962 : 1, 2, 13, 26, 37, 74, 481, 962
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,954,765,962,221, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
954:2x 3x 3x 53
765:3x 3x 5x 17
962:2x 13x 37
221:13x 17
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 3x 3x 5x 13x 13x 17 = 517140
Therefore, the value for common factors is 517140.
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 = 80682714122400/(1x517140)
LCM = 80682714122400/517140
LCM = 156017160
Thus, we can understand that the LCM of 520,954,765,962,221 is 156017160.
