GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(188, 664) = 31208
GCD(188, 664) = ( 188 x 664 ) / 31208
= 188 / 664
= 188
Step2:
LCM(4, 455) = 1820
GCD(4, 455) = ( 4 x 455 ) / 1820
= 4 / 455
= 4
Step3:
LCM(1, 663) = 663
GCD(1, 663) = ( 1 x 663 ) / 663
= 1 / 663
= 1
So, Greatest Common Divisor of 188, 664, 455, 663 is 1
