GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(266, 644) = 12236
GCD(266, 644) = ( 266 x 644 ) / 12236
= 266 / 644
= 266
Step2:
LCM(14, 217) = 434
GCD(14, 217) = ( 14 x 217 ) / 434
= 14 / 217
= 14
Step3:
LCM(7, 658) = 658
GCD(7, 658) = ( 7 x 658 ) / 658
= 7 / 658
= 7
So, Greatest Common Divisor of 266, 644, 217, 658 is 7
