Given numbers are 189, 807, 769, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(189, 807) = 50841
GCD(189, 807) = ( 189 x 807 ) / 50841
= 189 / 807
= 189
Step2:
LCM(3, 769) = 2307
GCD(3, 769) = ( 3 x 769 ) / 2307
= 3 / 769
= 3
Step3:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
So, Greatest Common Divisor of 189, 807, 769, 122 is 1
