The LCF of 4 & 7 is... 1 ! There are no other common factors.
28 is the LCM of 4 and 7 , the smallest number divisible by both.
28
Because 7 is prime, the highest, lowest and only common factor of 15 and 7 is 1 (one).
The lowest common factor of 6, 4 and 7 is 84.
84
They are factors of 28 as 28 = 4 x 7 which is also the lowest common multiple of both numbers.
The lowest common factor of any set of positive integers is 1.
The factors of 4 are 1, 2, and 4. The factors of 7 are 1 and 7. The only common factor is 1.
28 is the LCM of 4 and 7 , the smallest number divisible by both.
the LOWEST common multiple of 4 and 7 is 28
1 is alway the lowest common factor so I am not for sure if that's what you are looking for. and 6 and 7 do not have any other common factors.
28
Because 7 is prime, the highest, lowest and only common factor of 15 and 7 is 1 (one).
The common factors of 34, 51, and 85 are: 1 and 17
lcm(2, 4, 7) = 28.
The lowest common factor of 6, 4 and 7 is 84.
19 and 7 are both prime numbers, so that cannot share any factors, the lowest common multiple will therefore be arrived at by multiplying 19 by 7 = 133
