Given numbers are 503, 398, 546, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(503, 398) = 200194
GCD(503, 398) = ( 503 x 398 ) / 200194
= 503 / 398
= 503
Step2:
LCM(1, 546) = 546
GCD(1, 546) = ( 1 x 546 ) / 546
= 1 / 546
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 503, 398, 546, 646 is 1
