Given numbers are 803, 420, 145, 375
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(803, 420) = 337260
GCD(803, 420) = ( 803 x 420 ) / 337260
= 803 / 420
= 803
Step2:
LCM(1, 145) = 145
GCD(1, 145) = ( 1 x 145 ) / 145
= 1 / 145
= 1
Step3:
LCM(1, 375) = 375
GCD(1, 375) = ( 1 x 375 ) / 375
= 1 / 375
= 1
So, Greatest Common Divisor of 803, 420, 145, 375 is 1
