Given numbers are 220, 785, 122, 777

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

Apply this formula for all numbers.

Step1:

LCM(220, 785) = 34540

GCD(220, 785) = ( 220 x 785 ) / 34540

= 220 / 785

= 220

Step2:

LCM(5, 122) = 610

GCD(5, 122) = ( 5 x 122 ) / 610

= 5 / 122

= 5

Step3:

LCM(1, 777) = 777

GCD(1, 777) = ( 1 x 777 ) / 777

= 1 / 777

= 1

So, Greatest Common Divisor of 220, 785, 122, 777 is 1
