Given numbers are 188, 109, 915, 457
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(188, 109) = 20492
GCD(188, 109) = ( 188 x 109 ) / 20492
= 188 / 109
= 188
Step2:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
Step3:
LCM(1, 457) = 457
GCD(1, 457) = ( 1 x 457 ) / 457
= 1 / 457
= 1
So, Greatest Common Divisor of 188, 109, 915, 457 is 1
