Find LCM of 208,988,142,272,421 with Prime Factorization
2 | 208, 988, 142, 272, 421 |
2 | 104, 494, 71, 136, 421 |
2 | 52, 247, 71, 68, 421 |
2 | 26, 247, 71, 34, 421 |
13 | 13, 247, 71, 17, 421 |
1, 19, 71, 17, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 13 x 1 x 19 x 71 x 17 x 421 = 2008196944
Therefore, the lowest common multiple of 208,988,142,272,421 is 2008196944.
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.
208 x 988 x 142 x 272 x 421 = 3341639714816
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.
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
142 : 1, 2, 71, 142
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 208,988,142,272,421, is 1.
Now, the common factors can be found like this.
208:2x 2x 2x 2x 13
988:2x 2x 13x 19
142:2x 71
272:2x 2x 2x 2x 17
421:421
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 2x 2x 13 = 1664
Therefore, the value for common factors is 1664.
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 = 3341639714816/(1x1664)
LCM = 3341639714816/1664
LCM = 2008196944
Thus, we can understand that the LCM of 208,988,142,272,421 is 2008196944.
