GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 117) = 25155
GCD(215, 117) = ( 215 x 117 ) / 25155
= 215 / 117
= 215
Step2:
LCM(1, 982) = 982
GCD(1, 982) = ( 1 x 982 ) / 982
= 1 / 982
= 1
Step3:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
So, Greatest Common Divisor of 215, 117, 982, 660 is 1
