Given numbers are 169, 138, 708, 439
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 138) = 23322
GCD(169, 138) = ( 169 x 138 ) / 23322
= 169 / 138
= 169
Step2:
LCM(1, 708) = 708
GCD(1, 708) = ( 1 x 708 ) / 708
= 1 / 708
= 1
Step3:
LCM(1, 439) = 439
GCD(1, 439) = ( 1 x 439 ) / 439
= 1 / 439
= 1
So, Greatest Common Divisor of 169, 138, 708, 439 is 1
