Given numbers are 581, 420, 114, 178
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(581, 420) = 34860
GCD(581, 420) = ( 581 x 420 ) / 34860
= 581 / 420
= 581
Step2:
LCM(7, 114) = 798
GCD(7, 114) = ( 7 x 114 ) / 798
= 7 / 114
= 7
Step3:
LCM(1, 178) = 178
GCD(1, 178) = ( 1 x 178 ) / 178
= 1 / 178
= 1
So, Greatest Common Divisor of 581, 420, 114, 178 is 1
