Given numbers are 776, 148, 664, 561

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

Apply this formula for all numbers.

Step1:

LCM(776, 148) = 28712

GCD(776, 148) = ( 776 x 148 ) / 28712

= 776 / 148

= 776

Step2:

LCM(4, 664) = 664

GCD(4, 664) = ( 4 x 664 ) / 664

= 4 / 664

= 4

Step3:

LCM(4, 561) = 2244

GCD(4, 561) = ( 4 x 561 ) / 2244

= 4 / 561

= 4

So, Greatest Common Divisor of 776, 148, 664, 561 is 1
