Given numbers are 608, 644, 400, 693
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(608, 644) = 97888
GCD(608, 644) = ( 608 x 644 ) / 97888
= 608 / 644
= 608
Step2:
LCM(4, 400) = 400
GCD(4, 400) = ( 4 x 400 ) / 400
= 4 / 400
= 4
Step3:
LCM(4, 693) = 2772
GCD(4, 693) = ( 4 x 693 ) / 2772
= 4 / 693
= 4
So, Greatest Common Divisor of 608, 644, 400, 693 is 1
