GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 988) = 159068
GCD(644, 988) = ( 644 x 988 ) / 159068
= 644 / 988
= 644
Step2:
LCM(4, 401) = 1604
GCD(4, 401) = ( 4 x 401 ) / 1604
= 4 / 401
= 4
Step3:
LCM(1, 574) = 574
GCD(1, 574) = ( 1 x 574 ) / 574
= 1 / 574
= 1
So, Greatest Common Divisor of 644, 988, 401, 574 is 1
