GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 918) = 909738
GCD(991, 918) = ( 991 x 918 ) / 909738
= 991 / 918
= 991
Step2:
LCM(1, 494) = 494
GCD(1, 494) = ( 1 x 494 ) / 494
= 1 / 494
= 1
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 991, 918, 494, 142 is 1
