Given numbers are 147, 180, 178, 494
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(147, 180) = 8820
GCD(147, 180) = ( 147 x 180 ) / 8820
= 147 / 180
= 147
Step2:
LCM(3, 178) = 534
GCD(3, 178) = ( 3 x 178 ) / 534
= 3 / 178
= 3
Step3:
LCM(1, 494) = 494
GCD(1, 494) = ( 1 x 494 ) / 494
= 1 / 494
= 1
So, Greatest Common Divisor of 147, 180, 178, 494 is 1
