Given numbers are 635,626,340,646
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 635,626,340,646 is 256791460.
Find LCM of 635,626,340,646 with Prime Factorization
2 | 635, 626, 340, 646 |
5 | 635, 313, 170, 323 |
17 | 127, 313, 34, 323 |
127, 313, 2, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 17 x 127 x 313 x 2 x 19 = 256791460
Therefore, the lowest common multiple of 635,626,340,646 is 256791460.
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.
635 x 626 x 340 x 646 = 87309096400
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.
635 : 1, 5, 127, 635
626 : 1, 2, 313, 626
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
646 : 1, 2, 17, 19, 34, 38, 323, 646
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 635,626,340,646, is 1.
Now, the common factors can be found like this.
635:5x 127
626:2x 313
340:2x 2x 5x 17
646:2x 17x 19
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 5x 17 = 340
Therefore, the value for common factors is 340.
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 = 87309096400/(1x340)
LCM = 87309096400/340
LCM = 256791460
Thus, we can understand that the LCM of 635,626,340,646 is 256791460.
