Given numbers are 218, 109, 769, 172

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

Apply this formula for all numbers.

Step1:

LCM(218, 109) = 218

GCD(218, 109) = ( 218 x 109 ) / 218

= 218 / 109

= 218

Step2:

LCM(109, 769) = 83821

GCD(109, 769) = ( 109 x 769 ) / 83821

= 109 / 769

= 109

Step3:

LCM(1, 172) = 172

GCD(1, 172) = ( 1 x 172 ) / 172

= 1 / 172

= 1

So, Greatest Common Divisor of 218, 109, 769, 172 is 1
