Given numbers are 218, 745, 778, 662

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

Apply this formula for all numbers.

Step1:

LCM(218, 745) = 162410

GCD(218, 745) = ( 218 x 745 ) / 162410

= 218 / 745

= 218

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 662) = 662

GCD(1, 662) = ( 1 x 662 ) / 662

= 1 / 662

= 1

So, Greatest Common Divisor of 218, 745, 778, 662 is 1
