GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(644, 159) = 102396
GCD(644, 159) = ( 644 x 159 ) / 102396
= 644 / 159
= 644
Step2:
LCM(1, 203) = 203
GCD(1, 203) = ( 1 x 203 ) / 203
= 1 / 203
= 1
Step3:
LCM(1, 176) = 176
GCD(1, 176) = ( 1 x 176 ) / 176
= 1 / 176
= 1
So, Greatest Common Divisor of 644, 159, 203, 176 is 1
