Find LCM of 494,520,188,678,421 with Prime Factorization
2 | 494, 520, 188, 678, 421 |
2 | 247, 260, 94, 339, 421 |
13 | 247, 130, 47, 339, 421 |
19, 10, 47, 339, 421 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 19 x 10 x 47 x 339 x 421 = 66272994840
Therefore, the lowest common multiple of 494,520,188,678,421 is 66272994840.
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.
494 x 520 x 188 x 678 x 421 = 13784782926720
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.
494 : 1, 2, 13, 19, 26, 38, 247, 494
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
188 : 1, 2, 4, 47, 94, 188
678 : 1, 2, 3, 6, 113, 226, 339, 678
421 : 1, 421
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 494,520,188,678,421, is 1.
Now, the common factors can be found like this.
494:2x 13x 19
520:2x 2x 2x 5x 13
188:2x 2x 47
678:2x 3x 113
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 13 = 208
Therefore, the value for common factors is 208.
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 = 13784782926720/(1x208)
LCM = 13784782926720/208
LCM = 66272994840
Thus, we can understand that the LCM of 494,520,188,678,421 is 66272994840.
