Given numbers are 628,252,396,178
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,252,396,178 is 38733156.
Find LCM of 628,252,396,178 with Prime Factorization
2 | 628, 252, 396, 178 |
2 | 314, 126, 198, 89 |
3 | 157, 63, 99, 89 |
3 | 157, 21, 33, 89 |
157, 7, 11, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 157 x 7 x 11 x 89 = 38733156
Therefore, the lowest common multiple of 628,252,396,178 is 38733156.
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.
628 x 252 x 396 x 178 = 11155148928
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.
628 : 1, 2, 4, 157, 314, 628
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
396 : 1, 2, 3, 4, 6, 9, 11, 12, 18, 22, 33, 36, 44, 66, 99, 132, 198, 396
178 : 1, 2, 89, 178
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,252,396,178, is 2.
Now, the common factors can be found like this.
628:2x 2x 157
252:2x 2x 3x 3x 7
396:2x 2x 3x 3x 11
178:2x 89
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 3x 3 = 144
Therefore, the value for common factors is 144.
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 = 11155148928/(2x144)
LCM = 11155148928/288
LCM = 38733156
Thus, we can understand that the LCM of 628,252,396,178 is 38733156.
