Given numbers are 401,401,255,421,578
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 401,401,255,421,578 is 1463678070.
Find LCM of 401,401,255,421,578 with Prime Factorization
17 | 401, 401, 255, 421, 578 |
401 | 401, 401, 15, 421, 34 |
1, 1, 15, 421, 34 |
Multiply the prime numbers at the bottom and the left side.
17 x 401 x 1 x 1 x 15 x 421 x 34 = 1463678070
Therefore, the lowest common multiple of 401,401,255,421,578 is 1463678070.
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 401 x 255 x 421 x 578 = 9977893403190
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
401 : 1, 401
255 : 1, 3, 5, 15, 17, 51, 85, 255
421 : 1, 421
578 : 1, 2, 17, 34, 289, 578
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 401,401,255,421,578, is 1.
Now, the common factors can be found like this.
401:401
401:401
255:3x 5x 17
421:421
578:2x 17x 17
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
17x 401 = 6817
Therefore, the value for common factors is 6817.
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 = 9977893403190/(1x6817)
LCM = 9977893403190/6817
LCM = 1463678070
Thus, we can understand that the LCM of 401,401,255,421,578 is 1463678070.
