GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(745, 665) = 99085
GCD(745, 665) = ( 745 x 665 ) / 99085
= 745 / 665
= 745
Step2:
LCM(5, 685) = 685
GCD(5, 685) = ( 5 x 685 ) / 685
= 5 / 685
= 5
Step3:
LCM(5, 445) = 445
GCD(5, 445) = ( 5 x 445 ) / 445
= 5 / 445
= 5
So, Greatest Common Divisor of 745, 665, 685, 445 is 5
