Given numbers are 626,686,295,938,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 626,686,295,938,320 is 135804840640.
Find LCM of 626,686,295,938,320 with Prime Factorization
| 2 | 626, 686, 295, 938, 320 |
| 5 | 313, 343, 295, 469, 160 |
| 7 | 313, 343, 59, 469, 32 |
| 313, 49, 59, 67, 32 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 313 x 49 x 59 x 67 x 32 = 135804840640
Therefore, the lowest common multiple of 626,686,295,938,320 is 135804840640.
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.
626 x 686 x 295 x 938 x 320 = 38025355379200
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.
626 : 1, 2, 313, 626
686 : 1, 2, 7, 14, 49, 98, 343, 686
295 : 1, 5, 59, 295
938 : 1, 2, 7, 14, 67, 134, 469, 938
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,686,295,938,320, is 1.
Now, the common factors can be found like this.
626:2x 313
686:2x 7x 7x 7
295:5x 59
938:2x 7x 67
320:2x 2x 2x 2x 2x 2x 5
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 38025355379200/(1x280)
LCM = 38025355379200/280
LCM = 135804840640
Thus, we can understand that the LCM of 626,686,295,938,320 is 135804840640.
