Given numbers are 392,892,252,194
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 392,892,252,194 is 76314168.
Find LCM of 392,892,252,194 with Prime Factorization
| 2 | 392, 892, 252, 194 |
| 2 | 196, 446, 126, 97 |
| 7 | 98, 223, 63, 97 |
| 14, 223, 9, 97 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 14 x 223 x 9 x 97 = 76314168
Therefore, the lowest common multiple of 392,892,252,194 is 76314168.
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.
392 x 892 x 252 x 194 = 17094373632
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.
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
892 : 1, 2, 4, 223, 446, 892
252 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 28, 36, 42, 63, 84, 126, 252
194 : 1, 2, 97, 194
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 392,892,252,194, is 2.
Now, the common factors can be found like this.
392:2x 2x 2x 7x 7
892:2x 2x 223
252:2x 2x 3x 3x 7
194:2x 97
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 7 = 112
Therefore, the value for common factors is 112.
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 = 17094373632/(2x112)
LCM = 17094373632/224
LCM = 76314168
Thus, we can understand that the LCM of 392,892,252,194 is 76314168.
