70, 75, 80, 85, 90 and 95.
345 ÷ 5 = 69→ previous multiple is 5 x (69-1) = 5 x 68 = 340.
What is the multiple of 4 and 5 between 19 and 50
A case could be made for all of them. 45 is the only multiple of 5.
All multiples of 5 end in 0 or 5. So, the only number between 102 and 108 which is a multiple of 5 is 105.
The only such number between 55 and 101 is 80.
345 ÷ 5 = 69→ previous multiple is 5 x (69-1) = 5 x 68 = 340.
69
5
None of them.
What is the multiple of 4 and 5 between 19 and 50
A case could be made for all of them. 45 is the only multiple of 5.
I think 5
Since 150 is a multiple of 5, it is automatically the LCM.
All multiples of 5 end in 0 or 5. So, the only number between 102 and 108 which is a multiple of 5 is 105.
5-5=0, so the is -69
These steps can reduce our work: First of all we will write all the even numbers between 89 and 97: 90, 92, 94 & 96. Then multiples of 5: 90 & 95. Multiples of 3: 90, 93 & 96 and also the multiple of 7 which is 91. There is no other number left between 89 & 97. Therefore, numbers between 89 & 97 are all composite numbers.
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.
