Given numbers are 838, 258, 218, 777

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

Apply this formula for all numbers.

Step1:

LCM(838, 258) = 108102

GCD(838, 258) = ( 838 x 258 ) / 108102

= 838 / 258

= 838

Step2:

LCM(2, 218) = 218

GCD(2, 218) = ( 2 x 218 ) / 218

= 2 / 218

= 2

Step3:

LCM(2, 777) = 1554

GCD(2, 777) = ( 2 x 777 ) / 1554

= 2 / 777

= 2

So, Greatest Common Divisor of 838, 258, 218, 777 is 1
