Given numbers are 782,161,272,956
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,161,272,956 is 10466288.
Find LCM of 782,161,272,956 with Prime Factorization
| 2 | 782, 161, 272, 956 |
| 2 | 391, 161, 136, 478 |
| 17 | 391, 161, 68, 239 |
| 23 | 23, 161, 4, 239 |
| 1, 7, 4, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 23 x 1 x 7 x 4 x 239 = 10466288
Therefore, the lowest common multiple of 782,161,272,956 is 10466288.
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.
782 x 161 x 272 x 956 = 32738548864
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
161 : 1, 7, 23, 161
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
956 : 1, 2, 4, 239, 478, 956
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,161,272,956, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
161:7x 23
272:2x 2x 2x 2x 17
956:2x 2x 239
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 17x 23 = 3128
Therefore, the value for common factors is 3128.
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 = 32738548864/(1x3128)
LCM = 32738548864/3128
LCM = 10466288
Thus, we can understand that the LCM of 782,161,272,956 is 10466288.
