Given numbers are 491, 157, 770, 754
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(491, 157) = 77087
GCD(491, 157) = ( 491 x 157 ) / 77087
= 491 / 157
= 491
Step2:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
Step3:
LCM(1, 754) = 754
GCD(1, 754) = ( 1 x 754 ) / 754
= 1 / 754
= 1
So, Greatest Common Divisor of 491, 157, 770, 754 is 1
