Given numbers are 180, 457, 818, 190
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(180, 457) = 82260
GCD(180, 457) = ( 180 x 457 ) / 82260
= 180 / 457
= 180
Step2:
LCM(1, 818) = 818
GCD(1, 818) = ( 1 x 818 ) / 818
= 1 / 818
= 1
Step3:
LCM(1, 190) = 190
GCD(1, 190) = ( 1 x 190 ) / 190
= 1 / 190
= 1
So, Greatest Common Divisor of 180, 457, 818, 190 is 1
