Given numbers are 421,387,169,865,966
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,387,169,865,966 is 7669229685390.
Find LCM of 421,387,169,865,966 with Prime Factorization
3 | 421, 387, 169, 865, 966 |
421, 129, 169, 865, 322 |
Multiply the prime numbers at the bottom and the left side.
3 x 421 x 129 x 169 x 865 x 322 = 7669229685390
Therefore, the lowest common multiple of 421,387,169,865,966 is 7669229685390.
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.
421 x 387 x 169 x 865 x 966 = 23007689056170
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.
421 : 1, 421
387 : 1, 3, 9, 43, 129, 387
169 : 1, 13, 169
865 : 1, 5, 173, 865
966 : 1, 2, 3, 6, 7, 14, 21, 23, 42, 46, 69, 138, 161, 322, 483, 966
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,387,169,865,966, is 1.
Now, the common factors can be found like this.
421:421
387:3x 3x 43
169:13x 13
865:5x 173
966:2x 3x 7x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 23007689056170/(1x3)
LCM = 23007689056170/3
LCM = 7669229685390
Thus, we can understand that the LCM of 421,387,169,865,966 is 7669229685390.
