Given numbers are 421, 121, 673, 528
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(421, 121) = 50941
GCD(421, 121) = ( 421 x 121 ) / 50941
= 421 / 121
= 421
Step2:
LCM(1, 673) = 673
GCD(1, 673) = ( 1 x 673 ) / 673
= 1 / 673
= 1
Step3:
LCM(1, 528) = 528
GCD(1, 528) = ( 1 x 528 ) / 528
= 1 / 528
= 1
So, Greatest Common Divisor of 421, 121, 673, 528 is 1
