Given numbers are 428, 417, 661, 332

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

Apply this formula for all numbers.

Step1:

LCM(428, 417) = 178476

GCD(428, 417) = ( 428 x 417 ) / 178476

= 428 / 417

= 428

Step2:

LCM(1, 661) = 661

GCD(1, 661) = ( 1 x 661 ) / 661

= 1 / 661

= 1

Step3:

LCM(1, 332) = 332

GCD(1, 332) = ( 1 x 332 ) / 332

= 1 / 332

= 1

So, Greatest Common Divisor of 428, 417, 661, 332 is 1
