7 can go into 23 with a remainder of 2, hence 23 is not a multiple of 7
The Least Common Multiple (LCM) of 23 and 7 is 161.
No,it is not: 163 divided by 7 is 23 with a remainder of 2. If there is a remainder it is not divisible by that number.
It is: (3*7)+2 = 23
A number that is not a multiple of 7 and is less than 100 is 23. To determine this, we can list multiples of 7 (such as 7, 14, 21, 28, etc.) and check for numbers below 100 that do not appear in that list. Since 23 is not divisible by 7, it fits the criteria perfectly.
Given that 168 = 23 × 3 × 7, find the lowest common multiple of 120 and 168.
It is: 161 which is the least common multiple of 7 and 23
The Least Common Multiple (LCM) for 30 23 47 7 is 227,010.
The Least Common Multiple (LCM) of 23 and 7 is 161.
The LCM of 23 and 7 is 161. The LCM of 2, 3 and 7 is 42.
Their product.
It is: 161
The sum of 7 times the last digit and the rest of the number is a multiple of 23
The least common multiple of 7,23,59 is 9,499.
No,it is not: 163 divided by 7 is 23 with a remainder of 2. If there is a remainder it is not divisible by that number.
It is: (3*7)+2 = 23
7 times 23. The product of 2 numbers is always a common multiple but not necessarily the least. Question for you : When is the LCM the product ? Think about the relation between the product, the LCM and the Greatest Common Factor.
LCM is 56, which is the multiple of the highest power of prime factors in the given numbers (23 x 7).
