Given numbers are 175, 217, 661, 749

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

Apply this formula for all numbers.

Step1:

LCM(175, 217) = 5425

GCD(175, 217) = ( 175 x 217 ) / 5425

= 175 / 217

= 175

Step2:

LCM(7, 661) = 4627

GCD(7, 661) = ( 7 x 661 ) / 4627

= 7 / 661

= 7

Step3:

LCM(1, 749) = 749

GCD(1, 749) = ( 1 x 749 ) / 749

= 1 / 749

= 1

So, Greatest Common Divisor of 175, 217, 661, 749 is 1
