Given numbers are 695, 840, 949, 942
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(695, 840) = 116760
GCD(695, 840) = ( 695 x 840 ) / 116760
= 695 / 840
= 695
Step2:
LCM(5, 949) = 4745
GCD(5, 949) = ( 5 x 949 ) / 4745
= 5 / 949
= 5
Step3:
LCM(1, 942) = 942
GCD(1, 942) = ( 1 x 942 ) / 942
= 1 / 942
= 1
So, Greatest Common Divisor of 695, 840, 949, 942 is 1
