Given numbers are 785,205,257,436,761
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,205,257,436,761 is 2744465544820.
Find LCM of 785,205,257,436,761 with Prime Factorization
| 5 | 785, 205, 257, 436, 761 |
| 157, 41, 257, 436, 761 |
Multiply the prime numbers at the bottom and the left side.
5 x 157 x 41 x 257 x 436 x 761 = 2744465544820
Therefore, the lowest common multiple of 785,205,257,436,761 is 2744465544820.
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.
785 x 205 x 257 x 436 x 761 = 13722327724100
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.
785 : 1, 5, 157, 785
205 : 1, 5, 41, 205
257 : 1, 257
436 : 1, 2, 4, 109, 218, 436
761 : 1, 761
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,205,257,436,761, is 1.
Now, the common factors can be found like this.
785:5x 157
205:5x 41
257:257
436:2x 2x 109
761:761
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5 = 5
Therefore, the value for common factors is 5.
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 = 13722327724100/(1x5)
LCM = 13722327724100/5
LCM = 2744465544820
Thus, we can understand that the LCM of 785,205,257,436,761 is 2744465544820.
