Given numbers are 62, 20, 40, 65
The list of prime factors of all numbers are
Prime factors of 62 are 2 x 31
Prime factors of 20 are 2 x 2 x 5
Prime factors of 40 are 2 x 2 x 2 x 5
Prime factors of 65 are 5 x 13
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 62, 20, 40, 65
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(62, 20) = 620
GCD(62, 20) = ( 62 x 20 ) / 620
= 62 / 20
= 62
Step2:
LCM(2, 40) = 40
GCD(2, 40) = ( 2 x 40 ) / 40
= 2 / 40
= 2
Step3:
LCM(2, 65) = 130
GCD(2, 65) = ( 2 x 65 ) / 130
= 2 / 65
= 2
So, Greatest Common Divisor of 62, 20, 40, 65 is 1
