Given numbers are 142,417,556,744,274
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 142,417,556,744,274 is 1005927432.
Find LCM of 142,417,556,744,274 with Prime Factorization
| 2 | 142, 417, 556, 744, 274 |
| 2 | 71, 417, 278, 372, 137 |
| 3 | 71, 417, 139, 186, 137 |
| 139 | 71, 139, 139, 62, 137 |
| 71, 1, 1, 62, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 139 x 71 x 1 x 1 x 62 x 137 = 1005927432
Therefore, the lowest common multiple of 142,417,556,744,274 is 1005927432.
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.
142 x 417 x 556 x 744 x 274 = 6711547826304
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.
142 : 1, 2, 71, 142
417 : 1, 3, 139, 417
556 : 1, 2, 4, 139, 278, 556
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
274 : 1, 2, 137, 274
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,417,556,744,274, is 1.
Now, the common factors can be found like this.
142:2x 71
417:3x 139
556:2x 2x 139
744:2x 2x 2x 3x 31
274:2x 137
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 2x 3x 139 = 6672
Therefore, the value for common factors is 6672.
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 = 6711547826304/(1x6672)
LCM = 6711547826304/6672
LCM = 1005927432
Thus, we can understand that the LCM of 142,417,556,744,274 is 1005927432.
