Given numbers are 735,688,851,161,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 735,688,851,161,642 is 46045703760.
Find LCM of 735,688,851,161,642 with Prime Factorization
| 2 | 735, 688, 851, 161, 642 |
| 3 | 735, 344, 851, 161, 321 |
| 7 | 245, 344, 851, 161, 107 |
| 23 | 35, 344, 851, 23, 107 |
| 35, 344, 37, 1, 107 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 23 x 35 x 344 x 37 x 1 x 107 = 46045703760
Therefore, the lowest common multiple of 735,688,851,161,642 is 46045703760.
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.
735 x 688 x 851 x 161 x 642 = 44480149832160
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.
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
851 : 1, 23, 37, 851
161 : 1, 7, 23, 161
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 735,688,851,161,642, is 1.
Now, the common factors can be found like this.
735:3x 5x 7x 7
688:2x 2x 2x 2x 43
851:23x 37
161:7x 23
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 7x 23 = 966
Therefore, the value for common factors is 966.
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 = 44480149832160/(1x966)
LCM = 44480149832160/966
LCM = 46045703760
Thus, we can understand that the LCM of 735,688,851,161,642 is 46045703760.
