Given numbers are 698,816,604,466,221
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 698,816,604,466,221 is 130254221136.
Find LCM of 698,816,604,466,221 with Prime Factorization
| 2 | 698, 816, 604, 466, 221 |
| 2 | 349, 408, 302, 233, 221 |
| 17 | 349, 204, 151, 233, 221 |
| 349, 12, 151, 233, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 349 x 12 x 151 x 233 x 13 = 130254221136
Therefore, the lowest common multiple of 698,816,604,466,221 is 130254221136.
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.
698 x 816 x 604 x 466 x 221 = 35429148148992
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.
698 : 1, 2, 349, 698
816 : 1, 2, 3, 4, 6, 8, 12, 16, 17, 24, 34, 48, 51, 68, 102, 136, 204, 272, 408, 816
604 : 1, 2, 4, 151, 302, 604
466 : 1, 2, 233, 466
221 : 1, 13, 17, 221
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 698,816,604,466,221, is 1.
Now, the common factors can be found like this.
698:2x 349
816:2x 2x 2x 2x 3x 17
604:2x 2x 151
466:2x 233
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 2x 2x 2x 17 = 272
Therefore, the value for common factors is 272.
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 = 35429148148992/(1x272)
LCM = 35429148148992/272
LCM = 130254221136
Thus, we can understand that the LCM of 698,816,604,466,221 is 130254221136.
