GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 226) = 48364
GCD(428, 226) = ( 428 x 226 ) / 48364
= 428 / 226
= 428
Step2:
LCM(2, 646) = 646
GCD(2, 646) = ( 2 x 646 ) / 646
= 2 / 646
= 2
Step3:
LCM(2, 528) = 528
GCD(2, 528) = ( 2 x 528 ) / 528
= 2 / 528
= 2
So, Greatest Common Divisor of 428, 226, 646, 528 is 2
