Given numbers are 648, 197, 415, 187
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(648, 197) = 127656
GCD(648, 197) = ( 648 x 197 ) / 127656
= 648 / 197
= 648
Step2:
LCM(1, 415) = 415
GCD(1, 415) = ( 1 x 415 ) / 415
= 1 / 415
= 1
Step3:
LCM(1, 187) = 187
GCD(1, 187) = ( 1 x 187 ) / 187
= 1 / 187
= 1
So, Greatest Common Divisor of 648, 197, 415, 187 is 1
