Given numbers are 401,620,794,151,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,620,794,151,580 is 432216671060.
Find LCM of 401,620,794,151,580 with Prime Factorization
| 2 | 401, 620, 794, 151, 580 |
| 2 | 401, 310, 397, 151, 290 |
| 5 | 401, 155, 397, 151, 145 |
| 401, 31, 397, 151, 29 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 401 x 31 x 397 x 151 x 29 = 432216671060
Therefore, the lowest common multiple of 401,620,794,151,580 is 432216671060.
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.
401 x 620 x 794 x 151 x 580 = 17288666842400
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.
401 : 1, 401
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
794 : 1, 2, 397, 794
151 : 1, 151
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,620,794,151,580, is 1.
Now, the common factors can be found like this.
401:401
620:2x 2x 5x 31
794:2x 397
151:151
580:2x 2x 5x 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 2x 5 = 40
Therefore, the value for common factors is 40.
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 = 17288666842400/(1x40)
LCM = 17288666842400/40
LCM = 432216671060
Thus, we can understand that the LCM of 401,620,794,151,580 is 432216671060.
