Given numbers are 278, 196, 530, 307
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 196) = 27244
GCD(278, 196) = ( 278 x 196 ) / 27244
= 278 / 196
= 278
Step2:
LCM(2, 530) = 530
GCD(2, 530) = ( 2 x 530 ) / 530
= 2 / 530
= 2
Step3:
LCM(2, 307) = 614
GCD(2, 307) = ( 2 x 307 ) / 614
= 2 / 307
= 2
So, Greatest Common Divisor of 278, 196, 530, 307 is 1
