Given numbers are 697,988,338,477
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 697,988,338,477 is 4270231836.
Find LCM of 697,988,338,477 with Prime Factorization
| 2 | 697, 988, 338, 477 |
| 13 | 697, 494, 169, 477 |
| 697, 38, 13, 477 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 697 x 38 x 13 x 477 = 4270231836
Therefore, the lowest common multiple of 697,988,338,477 is 4270231836.
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.
697 x 988 x 338 x 477 = 111026027736
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.
697 : 1, 17, 41, 697
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
338 : 1, 2, 13, 26, 169, 338
477 : 1, 3, 9, 53, 159, 477
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 697,988,338,477, is 1.
Now, the common factors can be found like this.
697:17x 41
988:2x 2x 13x 19
338:2x 13x 13
477:3x 3x 53
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13 = 26
Therefore, the value for common factors is 26.
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 = 111026027736/(1x26)
LCM = 111026027736/26
LCM = 4270231836
Thus, we can understand that the LCM of 697,988,338,477 is 4270231836.
