Given numbers are 661,938,930,439,492
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 661,938,930,439,492 is 10378524703260.
Find LCM of 661,938,930,439,492 with Prime Factorization
| 2 | 661, 938, 930, 439, 492 |
| 3 | 661, 469, 465, 439, 246 |
| 661, 469, 155, 439, 82 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 661 x 469 x 155 x 439 x 82 = 10378524703260
Therefore, the lowest common multiple of 661,938,930,439,492 is 10378524703260.
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.
661 x 938 x 930 x 439 x 492 = 124542296439120
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.
661 : 1, 661
938 : 1, 2, 7, 14, 67, 134, 469, 938
930 : 1, 2, 3, 5, 6, 10, 15, 30, 31, 62, 93, 155, 186, 310, 465, 930
439 : 1, 439
492 : 1, 2, 3, 4, 6, 12, 41, 82, 123, 164, 246, 492
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 661,938,930,439,492, is 1.
Now, the common factors can be found like this.
661:661
938:2x 7x 67
930:2x 3x 5x 31
439:439
492:2x 2x 3x 41
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 3 = 12
Therefore, the value for common factors is 12.
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 = 124542296439120/(1x12)
LCM = 124542296439120/12
LCM = 10378524703260
Thus, we can understand that the LCM of 661,938,930,439,492 is 10378524703260.
