Given numbers are 761, 580, 661, 407

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

Apply this formula for all numbers.

Step1:

LCM(761, 580) = 441380

GCD(761, 580) = ( 761 x 580 ) / 441380

= 761 / 580

= 761

Step2:

LCM(1, 661) = 661

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

= 1 / 661

= 1

Step3:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

So, Greatest Common Divisor of 761, 580, 661, 407 is 1
