Given numbers are 69,78,76,92,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 69,78,76,92,462 is 5249244.
Find LCM of 69,78,76,92,462 with Prime Factorization
2 | 69, 78, 76, 92, 462 |
2 | 69, 39, 38, 46, 231 |
3 | 69, 39, 19, 23, 231 |
23 | 23, 13, 19, 23, 77 |
1, 13, 19, 1, 77 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 23 x 1 x 13 x 19 x 1 x 77 = 5249244
Therefore, the lowest common multiple of 69,78,76,92,462 is 5249244.
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.
69 x 78 x 76 x 92 x 462 = 17385496128
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.
69 : 1, 3, 23, 69
78 : 1, 2, 3, 6, 13, 26, 39, 78
76 : 1, 2, 4, 19, 38, 76
92 : 1, 2, 4, 23, 46, 92
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 69,78,76,92,462, is 1.
Now, the common factors can be found like this.
69:3x 23
78:2x 3x 13
76:2x 2x 19
92:2x 2x 23
462:2x 3x 7x 11
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 3x 23 = 3312
Therefore, the value for common factors is 3312.
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 = 17385496128/(1x3312)
LCM = 17385496128/3312
LCM = 5249244
Thus, we can understand that the LCM of 69,78,76,92,462 is 5249244.
