Given numbers are 166, 791, 376, 644

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(166, 791) = 131306

GCD(166, 791) = ( 166 x 791 ) / 131306

= 166 / 791

= 166

Step2:

LCM(1, 376) = 376

GCD(1, 376) = ( 1 x 376 ) / 376

= 1 / 376

= 1

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 166, 791, 376, 644 is 1
