Given numbers are 212, 485, 631, 378
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(212, 485) = 102820
GCD(212, 485) = ( 212 x 485 ) / 102820
= 212 / 485
= 212
Step2:
LCM(1, 631) = 631
GCD(1, 631) = ( 1 x 631 ) / 631
= 1 / 631
= 1
Step3:
LCM(1, 378) = 378
GCD(1, 378) = ( 1 x 378 ) / 378
= 1 / 378
= 1
So, Greatest Common Divisor of 212, 485, 631, 378 is 1
