GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(212, 248) = 13144
GCD(212, 248) = ( 212 x 248 ) / 13144
= 212 / 248
= 212
Step2:
LCM(4, 664) = 664
GCD(4, 664) = ( 4 x 664 ) / 664
= 4 / 664
= 4
Step3:
LCM(4, 338) = 676
GCD(4, 338) = ( 4 x 338 ) / 676
= 4 / 338
= 4
So, Greatest Common Divisor of 212, 248, 664, 338 is 2
