GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(645, 834) = 179310
GCD(645, 834) = ( 645 x 834 ) / 179310
= 645 / 834
= 645
Step2:
LCM(3, 809) = 2427
GCD(3, 809) = ( 3 x 809 ) / 2427
= 3 / 809
= 3
Step3:
LCM(1, 528) = 528
GCD(1, 528) = ( 1 x 528 ) / 528
= 1 / 528
= 1
So, Greatest Common Divisor of 645, 834, 809, 528 is 1
