Given numbers are 803, 976, 368, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(803, 976) = 783728
GCD(803, 976) = ( 803 x 976 ) / 783728
= 803 / 976
= 803
Step2:
LCM(1, 368) = 368
GCD(1, 368) = ( 1 x 368 ) / 368
= 1 / 368
= 1
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 803, 976, 368, 420 is 1
