Given numbers are 770, 850, 170, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 850) = 65450
GCD(770, 850) = ( 770 x 850 ) / 65450
= 770 / 850
= 770
Step2:
LCM(10, 170) = 170
GCD(10, 170) = ( 10 x 170 ) / 170
= 10 / 170
= 10
Step3:
LCM(10, 991) = 9910
GCD(10, 991) = ( 10 x 991 ) / 9910
= 10 / 991
= 10
So, Greatest Common Divisor of 770, 850, 170, 991 is 1
