The LCM of 221,340,653,140,637 is 141426740.
Find LCM of 221,340,653,140,637 with Prime Factorization
| 2 | 221, 340, 653, 140, 637 |
| 2 | 221, 170, 653, 70, 637 |
| 5 | 221, 85, 653, 35, 637 |
| 7 | 221, 17, 653, 7, 637 |
| 13 | 221, 17, 653, 1, 91 |
| 17 | 17, 17, 653, 1, 7 |
| 1, 1, 653, 1, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 13 x 17 x 1 x 1 x 653 x 1 x 7 = 141426740
Therefore, the lowest common multiple of 221,340,653,140,637 is 141426740.
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.
221 x 340 x 653 x 140 x 637 = 4375743335600
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.
221 : 1, 13, 17, 221
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
653 : 1, 653
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
637 : 1, 7, 13, 49, 91, 637
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 221,340,653,140,637, is 1.
Now, the common factors can be found like this.
221:13x 17
340:2x 2x 5x 17
653:653
140:2x 2x 5x 7
637:7x 7x 13
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 5x 7x 13x 17 = 30940
Therefore, the value for common factors is 30940.
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 = 4375743335600/(1x30940)
LCM = 4375743335600/30940
LCM = 141426740
Thus, we can understand that the LCM of 221,340,653,140,637 is 141426740.
