Given numbers are 889,981,662,515,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 889,981,662,515,620 is 18434343524940.
Find LCM of 889,981,662,515,620 with Prime Factorization
| 2 | 889, 981, 662, 515, 620 |
| 5 | 889, 981, 331, 515, 310 |
| 889, 981, 331, 103, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 889 x 981 x 331 x 103 x 62 = 18434343524940
Therefore, the lowest common multiple of 889,981,662,515,620 is 18434343524940.
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.
889 x 981 x 662 x 515 x 620 = 184343435249400
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.
889 : 1, 7, 127, 889
981 : 1, 3, 9, 109, 327, 981
662 : 1, 2, 331, 662
515 : 1, 5, 103, 515
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 889,981,662,515,620, is 1.
Now, the common factors can be found like this.
889:7x 127
981:3x 3x 109
662:2x 331
515:5x 103
620:2x 2x 5x 31
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 184343435249400/(1x10)
LCM = 184343435249400/10
LCM = 18434343524940
Thus, we can understand that the LCM of 889,981,662,515,620 is 18434343524940.
