Given numbers are 785, 985, 903, 253
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(785, 985) = 154645
GCD(785, 985) = ( 785 x 985 ) / 154645
= 785 / 985
= 785
Step2:
LCM(5, 903) = 4515
GCD(5, 903) = ( 5 x 903 ) / 4515
= 5 / 903
= 5
Step3:
LCM(1, 253) = 253
GCD(1, 253) = ( 1 x 253 ) / 253
= 1 / 253
= 1
So, Greatest Common Divisor of 785, 985, 903, 253 is 1
