Given numbers are 674, 698, 644, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(674, 698) = 235226
GCD(674, 698) = ( 674 x 698 ) / 235226
= 674 / 698
= 674
Step2:
LCM(2, 644) = 644
GCD(2, 644) = ( 2 x 644 ) / 644
= 2 / 644
= 2
Step3:
LCM(2, 815) = 1630
GCD(2, 815) = ( 2 x 815 ) / 1630
= 2 / 815
= 2
So, Greatest Common Divisor of 674, 698, 644, 815 is 1
