GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 188) = 29140
GCD(155, 188) = ( 155 x 188 ) / 29140
= 155 / 188
= 155
Step2:
LCM(1, 899) = 899
GCD(1, 899) = ( 1 x 899 ) / 899
= 1 / 899
= 1
Step3:
LCM(1, 660) = 660
GCD(1, 660) = ( 1 x 660 ) / 660
= 1 / 660
= 1
So, Greatest Common Divisor of 155, 188, 899, 660 is 1
