Given numbers are 122,980,336,645,889
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 122,980,336,645,889 is 3917502960.
Find LCM of 122,980,336,645,889 with Prime Factorization
| 2 | 122, 980, 336, 645, 889 |
| 2 | 61, 490, 168, 645, 889 |
| 3 | 61, 245, 84, 645, 889 |
| 5 | 61, 245, 28, 215, 889 |
| 7 | 61, 49, 28, 43, 889 |
| 61, 7, 4, 43, 127 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 61 x 7 x 4 x 43 x 127 = 3917502960
Therefore, the lowest common multiple of 122,980,336,645,889 is 3917502960.
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.
122 x 980 x 336 x 645 x 889 = 23034917404800
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.
122 : 1, 2, 61, 122
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
336 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 16, 21, 24, 28, 42, 48, 56, 84, 112, 168, 336
645 : 1, 3, 5, 15, 43, 129, 215, 645
889 : 1, 7, 127, 889
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 122,980,336,645,889, is 1.
Now, the common factors can be found like this.
122:2x 61
980:2x 2x 5x 7x 7
336:2x 2x 2x 2x 3x 7
645:3x 5x 43
889:7x 127
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 2x 3x 5x 7x 7 = 5880
Therefore, the value for common factors is 5880.
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 = 23034917404800/(1x5880)
LCM = 23034917404800/5880
LCM = 3917502960
Thus, we can understand that the LCM of 122,980,336,645,889 is 3917502960.
