Given numbers are 727,781,220
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 727,781,220 is 11355740.
Find LCM of 727,781,220 with Prime Factorization
11 | 727, 781, 220 |
727, 71, 20 |
Multiply the prime numbers at the bottom and the left side.
11 x 727 x 71 x 20 = 11355740
Therefore, the lowest common multiple of 727,781,220 is 11355740.
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.
727 x 781 x 220 = 124913140
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.
727 : 1, 727
781 : 1, 11, 71, 781
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 727,781,220, is 1.
Now, the common factors can be found like this.
727:727
781:11x 71
220:2x 2x 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.
11 = 11
Therefore, the value for common factors is 11.
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 = 124913140/(1x11)
LCM = 124913140/11
LCM = 11355740
Thus, we can understand that the LCM of 727,781,220 is 11355740.
