GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(265, 665) = 35245
GCD(265, 665) = ( 265 x 665 ) / 35245
= 265 / 665
= 265
Step2:
LCM(5, 815) = 815
GCD(5, 815) = ( 5 x 815 ) / 815
= 5 / 815
= 5
Step3:
LCM(5, 220) = 220
GCD(5, 220) = ( 5 x 220 ) / 220
= 5 / 220
= 5
So, Greatest Common Divisor of 265, 665, 815, 220 is 5
