GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(188, 939) = 176532
GCD(188, 939) = ( 188 x 939 ) / 176532
= 188 / 939
= 188
Step2:
LCM(1, 642) = 642
GCD(1, 642) = ( 1 x 642 ) / 642
= 1 / 642
= 1
Step3:
LCM(1, 452) = 452
GCD(1, 452) = ( 1 x 452 ) / 452
= 1 / 452
= 1
So, Greatest Common Divisor of 188, 939, 642, 452 is 1
