Given numbers are 734,689,661,242
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 734,689,661,242 is 40448471206.
Find LCM of 734,689,661,242 with Prime Factorization
| 2 | 734, 689, 661, 242 |
| 367, 689, 661, 121 |
Multiply the prime numbers at the bottom and the left side.
2 x 367 x 689 x 661 x 121 = 40448471206
Therefore, the lowest common multiple of 734,689,661,242 is 40448471206.
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.
734 x 689 x 661 x 242 = 80896942412
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.
734 : 1, 2, 367, 734
689 : 1, 13, 53, 689
661 : 1, 661
242 : 1, 2, 11, 22, 121, 242
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 734,689,661,242, is 1.
Now, the common factors can be found like this.
734:2x 367
689:13x 53
661:661
242:2x 11x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 80896942412/(1x2)
LCM = 80896942412/2
LCM = 40448471206
Thus, we can understand that the LCM of 734,689,661,242 is 40448471206.
