Given numbers are 209,577,781,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 209,577,781,247 is 111307339.
Find LCM of 209,577,781,247 with Prime Factorization
11 | 209, 577, 781, 247 |
19 | 19, 577, 71, 247 |
1, 577, 71, 13 |
Multiply the prime numbers at the bottom and the left side.
11 x 19 x 1 x 577 x 71 x 13 = 111307339
Therefore, the lowest common multiple of 209,577,781,247 is 111307339.
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.
209 x 577 x 781 x 247 = 23263233851
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.
209 : 1, 11, 19, 209
577 : 1, 577
781 : 1, 11, 71, 781
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 209,577,781,247, is 1.
Now, the common factors can be found like this.
209:11x 19
577:577
781:11x 71
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
11x 19 = 209
Therefore, the value for common factors is 209.
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 = 23263233851/(1x209)
LCM = 23263233851/209
LCM = 111307339
Thus, we can understand that the LCM of 209,577,781,247 is 111307339.
