Given numbers are 522, 645, 278, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(522, 645) = 112230
GCD(522, 645) = ( 522 x 645 ) / 112230
= 522 / 645
= 522
Step2:
LCM(3, 278) = 834
GCD(3, 278) = ( 3 x 278 ) / 834
= 3 / 278
= 3
Step3:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
So, Greatest Common Divisor of 522, 645, 278, 163 is 1
