Given numbers are 985, 421, 470, 503
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 421) = 414685
GCD(985, 421) = ( 985 x 421 ) / 414685
= 985 / 421
= 985
Step2:
LCM(1, 470) = 470
GCD(1, 470) = ( 1 x 470 ) / 470
= 1 / 470
= 1
Step3:
LCM(1, 503) = 503
GCD(1, 503) = ( 1 x 503 ) / 503
= 1 / 503
= 1
So, Greatest Common Divisor of 985, 421, 470, 503 is 1
