GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(819, 907) = 742833
GCD(819, 907) = ( 819 x 907 ) / 742833
= 819 / 907
= 819
Step2:
LCM(1, 867) = 867
GCD(1, 867) = ( 1 x 867 ) / 867
= 1 / 867
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 819, 907, 867, 420 is 1
