Find LCM of 177,420,531,388,370 with Prime Factorization
2 | 177, 420, 531, 388, 370 |
2 | 177, 210, 531, 194, 185 |
3 | 177, 105, 531, 97, 185 |
5 | 59, 35, 177, 97, 185 |
59 | 59, 7, 177, 97, 37 |
1, 7, 3, 97, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 59 x 1 x 7 x 3 x 97 x 37 = 266806260
Therefore, the lowest common multiple of 177,420,531,388,370 is 266806260.
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.
177 x 420 x 531 x 388 x 370 = 5666964962400
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.
177 : 1, 3, 59, 177
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
531 : 1, 3, 9, 59, 177, 531
388 : 1, 2, 4, 97, 194, 388
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 177,420,531,388,370, is 1.
Now, the common factors can be found like this.
177:3x 59
420:2x 2x 3x 5x 7
531:3x 3x 59
388:2x 2x 97
370:2x 5x 37
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 3x 3x 5x 59 = 21240
Therefore, the value for common factors is 21240.
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 = 5666964962400/(1x21240)
LCM = 5666964962400/21240
LCM = 266806260
Thus, we can understand that the LCM of 177,420,531,388,370 is 266806260.
