Given numbers are 163, 308, 430, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(163, 308) = 50204
GCD(163, 308) = ( 163 x 308 ) / 50204
= 163 / 308
= 163
Step2:
LCM(1, 430) = 430
GCD(1, 430) = ( 1 x 430 ) / 430
= 1 / 430
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 163, 308, 430, 690 is 1
