GCD: 1
LCM: 170
The least common multiple of the numbers 34 and 5 is 170.
170
Their product.
170
If that's 34 and 5, you're looking for 500 multiples of 170 which starts with 170, 340, 510, 680 and keeps adding 170 until you get to 85,000. If that's 3, 4 and 5, you're looking for multiples of 60 which starts with 60, 120, 180, 240, 300, 360 and ends with 30,000.
Since 150 is a multiple of 5, it is automatically the LCM.
90. The Least Common Multiple of 2, 3 and 5 is 30 and the multiple of 30 that is between 80 and 100 is 90.
It is 95
