Given numbers are 737,938,861,931
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 737,938,861,931 is 168792162.
Find LCM of 737,938,861,931 with Prime Factorization
| 7 | 737, 938, 861, 931 |
| 67 | 737, 134, 123, 133 |
| 11, 2, 123, 133 |
Multiply the prime numbers at the bottom and the left side.
7 x 67 x 11 x 2 x 123 x 133 = 168792162
Therefore, the lowest common multiple of 737,938,861,931 is 168792162.
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.
737 x 938 x 861 x 931 = 554144667846
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.
737 : 1, 11, 67, 737
938 : 1, 2, 7, 14, 67, 134, 469, 938
861 : 1, 3, 7, 21, 41, 123, 287, 861
931 : 1, 7, 19, 49, 133, 931
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 737,938,861,931, is 1.
Now, the common factors can be found like this.
737:11x 67
938:2x 7x 67
861:3x 7x 41
931:7x 7x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
7x 7x 67 = 3283
Therefore, the value for common factors is 3283.
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 = 554144667846/(1x3283)
LCM = 554144667846/3283
LCM = 168792162
Thus, we can understand that the LCM of 737,938,861,931 is 168792162.
