Find LCM of 722,883,897,138,221 with Prime Factorization
2 | 722, 883, 897, 138, 221 |
3 | 361, 883, 897, 69, 221 |
13 | 361, 883, 299, 23, 221 |
23 | 361, 883, 23, 23, 17 |
361, 883, 1, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 23 x 361 x 883 x 1 x 1 x 17 = 9721633974
Therefore, the lowest common multiple of 722,883,897,138,221 is 9721633974.
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.
722 x 883 x 897 x 138 x 221 = 17440611349356
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.
722 : 1, 2, 19, 38, 361, 722
883 : 1, 883
897 : 1, 3, 13, 23, 39, 69, 299, 897
138 : 1, 2, 3, 6, 23, 46, 69, 138
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 722,883,897,138,221, is 1.
Now, the common factors can be found like this.
722:2x 19x 19
883:883
897:3x 13x 23
138:2x 3x 23
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 3x 13x 23 = 1794
Therefore, the value for common factors is 1794.
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 = 17440611349356/(1x1794)
LCM = 17440611349356/1794
LCM = 9721633974
Thus, we can understand that the LCM of 722,883,897,138,221 is 9721633974.
