Given numbers are 521, 567, 778, 647

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

Apply this formula for all numbers.

Step1:

LCM(521, 567) = 295407

GCD(521, 567) = ( 521 x 567 ) / 295407

= 521 / 567

= 521

Step2:

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

= 1 / 778

= 1

Step3:

LCM(1, 647) = 647

GCD(1, 647) = ( 1 x 647 ) / 647

= 1 / 647

= 1

So, Greatest Common Divisor of 521, 567, 778, 647 is 1
