Given numbers are 474,377,221,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,377,221,655 is 1989802230.
Find LCM of 474,377,221,655 with Prime Factorization
| 13 | 474, 377, 221, 655 |
| 474, 29, 17, 655 |
Multiply the prime numbers at the bottom and the left side.
13 x 474 x 29 x 17 x 655 = 1989802230
Therefore, the lowest common multiple of 474,377,221,655 is 1989802230.
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.
474 x 377 x 221 x 655 = 25867428990
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
377 : 1, 13, 29, 377
221 : 1, 13, 17, 221
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,377,221,655, is 1.
Now, the common factors can be found like this.
474:2x 3x 79
377:13x 29
221:13x 17
655:5x 131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
13 = 13
Therefore, the value for common factors is 13.
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 = 25867428990/(1x13)
LCM = 25867428990/13
LCM = 1989802230
Thus, we can understand that the LCM of 474,377,221,655 is 1989802230.
