Given numbers are 851, 777, 921, 298
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(851, 777) = 17871
GCD(851, 777) = ( 851 x 777 ) / 17871
= 851 / 777
= 851
Step2:
LCM(37, 921) = 34077
GCD(37, 921) = ( 37 x 921 ) / 34077
= 37 / 921
= 37
Step3:
LCM(1, 298) = 298
GCD(1, 298) = ( 1 x 298 ) / 298
= 1 / 298
= 1
So, Greatest Common Divisor of 851, 777, 921, 298 is 1
