55, 110, 165, 220, 275, 330, 385, and etc. As long as it is a multiple of 55, you could also divide other numbers by 55, but it won't be a whole number.
The HCF of both numbers is 1
These numbers have no common factor, so the answer is 1.
220
Oh, dude, let me bust out my calculator for this intense math problem... Okay, so 4 goes into 220 like 55 times. Yeah, that's right, 55! So, if you ever find yourself wondering how many times 4 can cozy up to 220, just remember it's 55 times. Math, man, it's wild.
The LCM of the given numbers is 220
The LCM is 220
1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220.
1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220.
1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220.
5 goes into 45 and 55
Amicable numbers are pairs of numbers for which the sum of the proper divisors (the divisors except for the number itself) equals the other number in the pair. The smallest amicable pair is 220 and 284. The proper divisors of 220 are and the factors of 220 are 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, and 110, the sum of which is 284. The proper divisors of 284 are 1, 2, 4, 71, and 142, the sum of which is 220.
