Given numbers are 378, 331, 443, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 331) = 125118
GCD(378, 331) = ( 378 x 331 ) / 125118
= 378 / 331
= 378
Step2:
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
= 1 / 443
= 1
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 378, 331, 443, 220 is 1
