GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(810, 668) = 270540
GCD(810, 668) = ( 810 x 668 ) / 270540
= 810 / 668
= 810
Step2:
LCM(2, 544) = 544
GCD(2, 544) = ( 2 x 544 ) / 544
= 2 / 544
= 2
Step3:
LCM(2, 202) = 202
GCD(2, 202) = ( 2 x 202 ) / 202
= 2 / 202
= 2
So, Greatest Common Divisor of 810, 668, 544, 202 is 2
