GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(775, 915) = 141825
GCD(775, 915) = ( 775 x 915 ) / 141825
= 775 / 915
= 775
Step2:
LCM(5, 500) = 500
GCD(5, 500) = ( 5 x 500 ) / 500
= 5 / 500
= 5
Step3:
LCM(5, 420) = 420
GCD(5, 420) = ( 5 x 420 ) / 420
= 5 / 420
= 5
So, Greatest Common Divisor of 775, 915, 500, 420 is 5
