Given numbers are 403,143,393,550
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 403,143,393,550 is 87108450.
Find LCM of 403,143,393,550 with Prime Factorization
11 | 403, 143, 393, 550 |
13 | 403, 13, 393, 50 |
31, 1, 393, 50 |
Multiply the prime numbers at the bottom and the left side.
11 x 13 x 31 x 1 x 393 x 50 = 87108450
Therefore, the lowest common multiple of 403,143,393,550 is 87108450.
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.
403 x 143 x 393 x 550 = 12456508350
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.
403 : 1, 13, 31, 403
143 : 1, 11, 13, 143
393 : 1, 3, 131, 393
550 : 1, 2, 5, 10, 11, 22, 25, 50, 55, 110, 275, 550
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 403,143,393,550, is 1.
Now, the common factors can be found like this.
403:13x 31
143:11x 13
393:3x 131
550:2x 5x 5x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 13 = 143
Therefore, the value for common factors is 143.
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 = 12456508350/(1x143)
LCM = 12456508350/143
LCM = 87108450
Thus, we can understand that the LCM of 403,143,393,550 is 87108450.
