Given numbers are 410, 428, 420, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(410, 428) = 87740
GCD(410, 428) = ( 410 x 428 ) / 87740
= 410 / 428
= 410
Step2:
LCM(2, 420) = 420
GCD(2, 420) = ( 2 x 420 ) / 420
= 2 / 420
= 2
Step3:
LCM(2, 163) = 326
GCD(2, 163) = ( 2 x 163 ) / 326
= 2 / 163
= 2
So, Greatest Common Divisor of 410, 428, 420, 163 is 1
