Given numbers are 590, 245, 138, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(590, 245) = 28910
GCD(590, 245) = ( 590 x 245 ) / 28910
= 590 / 245
= 590
Step2:
LCM(5, 138) = 690
GCD(5, 138) = ( 5 x 138 ) / 690
= 5 / 138
= 5
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 590, 245, 138, 644 is 1
