Given numbers are 497, 146, 644, 659
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(497, 146) = 72562
GCD(497, 146) = ( 497 x 146 ) / 72562
= 497 / 146
= 497
Step2:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
Step3:
LCM(1, 659) = 659
GCD(1, 659) = ( 1 x 659 ) / 659
= 1 / 659
= 1
So, Greatest Common Divisor of 497, 146, 644, 659 is 1
