Given numbers are 166, 778, 621

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

Apply this formula for all numbers.

Step1:

LCM(166, 778) = 64574

GCD(166, 778) = ( 166 x 778 ) / 64574

= 166 / 778

= 166

Step2:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2

So, Greatest Common Divisor of 166, 778, 621 is 1
