Given numbers are 302, 628, 138, 245
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(302, 628) = 94828
GCD(302, 628) = ( 302 x 628 ) / 94828
= 302 / 628
= 302
Step2:
LCM(2, 138) = 138
GCD(2, 138) = ( 2 x 138 ) / 138
= 2 / 138
= 2
Step3:
LCM(2, 245) = 490
GCD(2, 245) = ( 2 x 245 ) / 490
= 2 / 245
= 2
So, Greatest Common Divisor of 302, 628, 138, 245 is 1
