Given numbers are 139, 428, 137, 291
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(139, 428) = 59492
GCD(139, 428) = ( 139 x 428 ) / 59492
= 139 / 428
= 139
Step2:
LCM(1, 137) = 137
GCD(1, 137) = ( 1 x 137 ) / 137
= 1 / 137
= 1
Step3:
LCM(1, 291) = 291
GCD(1, 291) = ( 1 x 291 ) / 291
= 1 / 291
= 1
So, Greatest Common Divisor of 139, 428, 137, 291 is 1
