Given numbers are 420, 762, 197, 447
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 762) = 53340
GCD(420, 762) = ( 420 x 762 ) / 53340
= 420 / 762
= 420
Step2:
LCM(6, 197) = 1182
GCD(6, 197) = ( 6 x 197 ) / 1182
= 6 / 197
= 6
Step3:
LCM(1, 447) = 447
GCD(1, 447) = ( 1 x 447 ) / 447
= 1 / 447
= 1
So, Greatest Common Divisor of 420, 762, 197, 447 is 1
