Given numbers are 917,278,138,493,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,278,138,493,278 is 8671817742.
Find LCM of 917,278,138,493,278 with Prime Factorization
2 | 917, 278, 138, 493, 278 |
139 | 917, 139, 69, 493, 139 |
917, 1, 69, 493, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 139 x 917 x 1 x 69 x 493 x 1 = 8671817742
Therefore, the lowest common multiple of 917,278,138,493,278 is 8671817742.
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.
917 x 278 x 138 x 493 x 278 = 4821530664552
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.
917 : 1, 7, 131, 917
278 : 1, 2, 139, 278
138 : 1, 2, 3, 6, 23, 46, 69, 138
493 : 1, 17, 29, 493
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,278,138,493,278, is 1.
Now, the common factors can be found like this.
917:7x 131
278:2x 139
138:2x 3x 23
493:17x 29
278:2x 139
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 139 = 556
Therefore, the value for common factors is 556.
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 = 4821530664552/(1x556)
LCM = 4821530664552/556
LCM = 8671817742
Thus, we can understand that the LCM of 917,278,138,493,278 is 8671817742.
