GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(913, 649) = 53867
GCD(913, 649) = ( 913 x 649 ) / 53867
= 913 / 649
= 913
Step2:
LCM(11, 434) = 4774
GCD(11, 434) = ( 11 x 434 ) / 4774
= 11 / 434
= 11
Step3:
LCM(1, 938) = 938
GCD(1, 938) = ( 1 x 938 ) / 938
= 1 / 938
= 1
So, Greatest Common Divisor of 913, 649, 434, 938 is 1
