Given numbers are 644, 992, 900, 765
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 992) = 159712
GCD(644, 992) = ( 644 x 992 ) / 159712
= 644 / 992
= 644
Step2:
LCM(4, 900) = 900
GCD(4, 900) = ( 4 x 900 ) / 900
= 4 / 900
= 4
Step3:
LCM(4, 765) = 3060
GCD(4, 765) = ( 4 x 765 ) / 3060
= 4 / 765
= 4
So, Greatest Common Divisor of 644, 992, 900, 765 is 1
