Given numbers are 270, 978, 972, 191
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(270, 978) = 44010
GCD(270, 978) = ( 270 x 978 ) / 44010
= 270 / 978
= 270
Step2:
LCM(6, 972) = 972
GCD(6, 972) = ( 6 x 972 ) / 972
= 6 / 972
= 6
Step3:
LCM(6, 191) = 1146
GCD(6, 191) = ( 6 x 191 ) / 1146
= 6 / 191
= 6
So, Greatest Common Divisor of 270, 978, 972, 191 is 1
