Given numbers are 245, 342, 531, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(245, 342) = 83790
GCD(245, 342) = ( 245 x 342 ) / 83790
= 245 / 342
= 245
Step2:
LCM(1, 531) = 531
GCD(1, 531) = ( 1 x 531 ) / 531
= 1 / 531
= 1
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 245, 342, 531, 139 is 1
