Given numbers are 770, 990, 297, 791
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(770, 990) = 6930
GCD(770, 990) = ( 770 x 990 ) / 6930
= 770 / 990
= 770
Step2:
LCM(110, 297) = 2970
GCD(110, 297) = ( 110 x 297 ) / 2970
= 110 / 297
= 110
Step3:
LCM(11, 791) = 8701
GCD(11, 791) = ( 11 x 791 ) / 8701
= 11 / 791
= 11
So, Greatest Common Divisor of 770, 990, 297, 791 is 1
