Given numbers are 856,691,706,893,988
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 856,691,706,893,988 is 2423937003592.
Find LCM of 856,691,706,893,988 with Prime Factorization
| 2 | 856, 691, 706, 893, 988 |
| 2 | 428, 691, 353, 893, 494 |
| 19 | 214, 691, 353, 893, 247 |
| 214, 691, 353, 47, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 214 x 691 x 353 x 47 x 13 = 2423937003592
Therefore, the lowest common multiple of 856,691,706,893,988 is 2423937003592.
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.
856 x 691 x 706 x 893 x 988 = 368438424545984
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.
856 : 1, 2, 4, 8, 107, 214, 428, 856
691 : 1, 691
706 : 1, 2, 353, 706
893 : 1, 19, 47, 893
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 856,691,706,893,988, is 1.
Now, the common factors can be found like this.
856:2x 2x 2x 107
691:691
706:2x 353
893:19x 47
988:2x 2x 13x 19
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 19 = 152
Therefore, the value for common factors is 152.
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 = 368438424545984/(1x152)
LCM = 368438424545984/152
LCM = 2423937003592
Thus, we can understand that the LCM of 856,691,706,893,988 is 2423937003592.
