GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(261, 831) = 72297
GCD(261, 831) = ( 261 x 831 ) / 72297
= 261 / 831
= 261
Step2:
LCM(3, 169) = 507
GCD(3, 169) = ( 3 x 169 ) / 507
= 3 / 169
= 3
Step3:
LCM(1, 945) = 945
GCD(1, 945) = ( 1 x 945 ) / 945
= 1 / 945
= 1
So, Greatest Common Divisor of 261, 831, 169, 945 is 1
