Given numbers are 389, 242, 253, 931
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(389, 242) = 94138
GCD(389, 242) = ( 389 x 242 ) / 94138
= 389 / 242
= 389
Step2:
LCM(1, 253) = 253
GCD(1, 253) = ( 1 x 253 ) / 253
= 1 / 253
= 1
Step3:
LCM(1, 931) = 931
GCD(1, 931) = ( 1 x 931 ) / 931
= 1 / 931
= 1
So, Greatest Common Divisor of 389, 242, 253, 931 is 1
