Given numbers are 654, 220, 236, 393

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

Apply this formula for all numbers.

Step1:

LCM(654, 220) = 71940

GCD(654, 220) = ( 654 x 220 ) / 71940

= 654 / 220

= 654

Step2:

LCM(2, 236) = 236

GCD(2, 236) = ( 2 x 236 ) / 236

= 2 / 236

= 2

Step3:

LCM(2, 393) = 786

GCD(2, 393) = ( 2 x 393 ) / 786

= 2 / 393

= 2

So, Greatest Common Divisor of 654, 220, 236, 393 is 1
