Given numbers are 307, 456, 656, 193
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(307, 456) = 139992
GCD(307, 456) = ( 307 x 456 ) / 139992
= 307 / 456
= 307
Step2:
LCM(1, 656) = 656
GCD(1, 656) = ( 1 x 656 ) / 656
= 1 / 656
= 1
Step3:
LCM(1, 193) = 193
GCD(1, 193) = ( 1 x 193 ) / 193
= 1 / 193
= 1
So, Greatest Common Divisor of 307, 456, 656, 193 is 1
