Given numbers are 734,836,477,145,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 734,836,477,145,638 is 21220651980.
Find LCM of 734,836,477,145,638 with Prime Factorization
2 | 734, 836, 477, 145, 638 |
11 | 367, 418, 477, 145, 319 |
29 | 367, 38, 477, 145, 29 |
367, 38, 477, 5, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 29 x 367 x 38 x 477 x 5 x 1 = 21220651980
Therefore, the lowest common multiple of 734,836,477,145,638 is 21220651980.
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.
734 x 836 x 477 x 145 x 638 = 27077551926480
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.
734 : 1, 2, 367, 734
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
477 : 1, 3, 9, 53, 159, 477
145 : 1, 5, 29, 145
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 734,836,477,145,638, is 1.
Now, the common factors can be found like this.
734:2x 367
836:2x 2x 11x 19
477:3x 3x 53
145:5x 29
638:2x 11x 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 11x 29 = 1276
Therefore, the value for common factors is 1276.
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 = 27077551926480/(1x1276)
LCM = 27077551926480/1276
LCM = 21220651980
Thus, we can understand that the LCM of 734,836,477,145,638 is 21220651980.
