Given numbers are 655,406,302,174
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,406,302,174 is 120466290.
Find LCM of 655,406,302,174 with Prime Factorization
| 2 | 655, 406, 302, 174 |
| 29 | 655, 203, 151, 87 |
| 655, 7, 151, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 29 x 655 x 7 x 151 x 3 = 120466290
Therefore, the lowest common multiple of 655,406,302,174 is 120466290.
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.
655 x 406 x 302 x 174 = 13974089640
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.
655 : 1, 5, 131, 655
406 : 1, 2, 7, 14, 29, 58, 203, 406
302 : 1, 2, 151, 302
174 : 1, 2, 3, 6, 29, 58, 87, 174
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,406,302,174, is 1.
Now, the common factors can be found like this.
655:5x 131
406:2x 7x 29
302:2x 151
174:2x 3x 29
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 29 = 116
Therefore, the value for common factors is 116.
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 = 13974089640/(1x116)
LCM = 13974089640/116
LCM = 120466290
Thus, we can understand that the LCM of 655,406,302,174 is 120466290.
