Given numbers are 196, 628, 444, 645
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(196, 628) = 30772
GCD(196, 628) = ( 196 x 628 ) / 30772
= 196 / 628
= 196
Step2:
LCM(4, 444) = 444
GCD(4, 444) = ( 4 x 444 ) / 444
= 4 / 444
= 4
Step3:
LCM(4, 645) = 2580
GCD(4, 645) = ( 4 x 645 ) / 2580
= 4 / 645
= 4
So, Greatest Common Divisor of 196, 628, 444, 645 is 1
