Given numbers are 187, 420, 430, 716
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(187, 420) = 78540
GCD(187, 420) = ( 187 x 420 ) / 78540
= 187 / 420
= 187
Step2:
LCM(1, 430) = 430
GCD(1, 430) = ( 1 x 430 ) / 430
= 1 / 430
= 1
Step3:
LCM(1, 716) = 716
GCD(1, 716) = ( 1 x 716 ) / 716
= 1 / 716
= 1
So, Greatest Common Divisor of 187, 420, 430, 716 is 1
