Given numbers are 981, 262, 622, 765
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(981, 262) = 257022
GCD(981, 262) = ( 981 x 262 ) / 257022
= 981 / 262
= 981
Step2:
LCM(1, 622) = 622
GCD(1, 622) = ( 1 x 622 ) / 622
= 1 / 622
= 1
Step3:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
So, Greatest Common Divisor of 981, 262, 622, 765 is 1
