Given numbers are 95, 90, 55, 20
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(95, 90) = 1710
GCD(95, 90) = ( 95 x 90 ) / 1710
= 95 / 90
= 95
Step2:
LCM(5, 55) = 55
GCD(5, 55) = ( 5 x 55 ) / 55
= 5 / 55
= 5
Step3:
LCM(5, 20) = 20
GCD(5, 20) = ( 5 x 20 ) / 20
= 5 / 20
= 5
So, Greatest Common Divisor of 95, 90, 55, 20 is 5
