Given numbers are 644, 575, 831, 386
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 575) = 16100
GCD(644, 575) = ( 644 x 575 ) / 16100
= 644 / 575
= 644
Step2:
LCM(23, 831) = 19113
GCD(23, 831) = ( 23 x 831 ) / 19113
= 23 / 831
= 23
Step3:
LCM(1, 386) = 386
GCD(1, 386) = ( 1 x 386 ) / 386
= 1 / 386
= 1
So, Greatest Common Divisor of 644, 575, 831, 386 is 1
