Given numbers are 553, 638, 186, 485
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(553, 638) = 352814
GCD(553, 638) = ( 553 x 638 ) / 352814
= 553 / 638
= 553
Step2:
LCM(1, 186) = 186
GCD(1, 186) = ( 1 x 186 ) / 186
= 1 / 186
= 1
Step3:
LCM(1, 485) = 485
GCD(1, 485) = ( 1 x 485 ) / 485
= 1 / 485
= 1
So, Greatest Common Divisor of 553, 638, 186, 485 is 1
