GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(924, 847) = 10164
GCD(924, 847) = ( 924 x 847 ) / 10164
= 924 / 847
= 924
Step2:
LCM(77, 994) = 10934
GCD(77, 994) = ( 77 x 994 ) / 10934
= 77 / 994
= 77
Step3:
LCM(7, 644) = 644
GCD(7, 644) = ( 7 x 644 ) / 644
= 7 / 644
= 7
So, Greatest Common Divisor of 924, 847, 994, 644 is 7
