Given numbers are 278, 139, 706, 613
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(278, 139) = 278
GCD(278, 139) = ( 278 x 139 ) / 278
= 278 / 139
= 278
Step2:
LCM(139, 706) = 98134
GCD(139, 706) = ( 139 x 706 ) / 98134
= 139 / 706
= 139
Step3:
LCM(1, 613) = 613
GCD(1, 613) = ( 1 x 613 ) / 613
= 1 / 613
= 1
So, Greatest Common Divisor of 278, 139, 706, 613 is 1
