Given numbers are 172,774,156,248
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 172,774,156,248 is 1247688.
Find LCM of 172,774,156,248 with Prime Factorization
2 | 172, 774, 156, 248 |
2 | 86, 387, 78, 124 |
3 | 43, 387, 39, 62 |
43 | 43, 129, 13, 62 |
1, 3, 13, 62 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 1 x 3 x 13 x 62 = 1247688
Therefore, the lowest common multiple of 172,774,156,248 is 1247688.
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.
172 x 774 x 156 x 248 = 5150456064
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.
172 : 1, 2, 4, 43, 86, 172
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
248 : 1, 2, 4, 8, 31, 62, 124, 248
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 172,774,156,248, is 2.
Now, the common factors can be found like this.
172:2x 2x 43
774:2x 3x 3x 43
156:2x 2x 3x 13
248:2x 2x 2x 31
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 43 = 2064
Therefore, the value for common factors is 2064.
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 = 5150456064/(2x2064)
LCM = 5150456064/4128
LCM = 1247688
Thus, we can understand that the LCM of 172,774,156,248 is 1247688.
