Given numbers are 294, 420, 211, 637
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(294, 420) = 2940
GCD(294, 420) = ( 294 x 420 ) / 2940
= 294 / 420
= 294
Step2:
LCM(42, 211) = 8862
GCD(42, 211) = ( 42 x 211 ) / 8862
= 42 / 211
= 42
Step3:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
So, Greatest Common Divisor of 294, 420, 211, 637 is 1
