Given numbers are 556, 644, 745, 170
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(556, 644) = 89516
GCD(556, 644) = ( 556 x 644 ) / 89516
= 556 / 644
= 556
Step2:
LCM(4, 745) = 2980
GCD(4, 745) = ( 4 x 745 ) / 2980
= 4 / 745
= 4
Step3:
LCM(1, 170) = 170
GCD(1, 170) = ( 1 x 170 ) / 170
= 1 / 170
= 1
So, Greatest Common Divisor of 556, 644, 745, 170 is 1
