The highest common multiple is an infinite number and probably not of much use to you.
The GCF is 5.
The LCM is 2015.
The GCF is 5.
The GCF is 5.
LCM of two numbers = product/HCF; 65 = 5 x 13, 155 = 5 x 31 so HCF is 5 and LCM is 65 x 155/5 = 2015
The factors of 65 are 1, 5, 13, 65 The factors of 155 are 1, 5, 31, 155 The largest matching number is 5. Therefore the GCF of 65 and 155 is 5.
Numbers don't stop. The highest multiple is infinitely high.
Least common multiple of 45 and 65 is 585.
The least common multiple of 50 and 65 is 650.
This cannot be determined because the common multiples of any two or more numbers are infinite.
The highest common factors of 65 and 185 is 5.
The Least Common Multiple (LCM) of (65,75) is 975.
Least common multiple of 65 and 78 is 390.
Least common multiple of 65 and 85 is 1105.
