Given numbers are 421,938,196,760,796
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 421,938,196,760,796 is 209035307320.
Find LCM of 421,938,196,760,796 with Prime Factorization
| 2 | 421, 938, 196, 760, 796 |
| 2 | 421, 469, 98, 380, 398 |
| 7 | 421, 469, 49, 190, 199 |
| 421, 67, 7, 190, 199 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 421 x 67 x 7 x 190 x 199 = 209035307320
Therefore, the lowest common multiple of 421,938,196,760,796 is 209035307320.
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.
421 x 938 x 196 x 760 x 796 = 46823908839680
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.
421 : 1, 421
938 : 1, 2, 7, 14, 67, 134, 469, 938
196 : 1, 2, 4, 7, 14, 28, 49, 98, 196
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
796 : 1, 2, 4, 199, 398, 796
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 421,938,196,760,796, is 1.
Now, the common factors can be found like this.
421:421
938:2x 7x 67
196:2x 2x 7x 7
760:2x 2x 2x 5x 19
796:2x 2x 199
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 2x 2x 2x 7 = 224
Therefore, the value for common factors is 224.
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 = 46823908839680/(1x224)
LCM = 46823908839680/224
LCM = 209035307320
Thus, we can understand that the LCM of 421,938,196,760,796 is 209035307320.
