Given numbers are 919, 921, 530, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(919, 921) = 846399
GCD(919, 921) = ( 919 x 921 ) / 846399
= 919 / 921
= 919
Step2:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 919, 921, 530, 644 is 1
