Given numbers are 625, 815, 778, 975

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

Apply this formula for all numbers.

Step1:

LCM(625, 815) = 101875

GCD(625, 815) = ( 625 x 815 ) / 101875

= 625 / 815

= 625

Step2:

LCM(5, 778) = 3890

GCD(5, 778) = ( 5 x 778 ) / 3890

= 5 / 778

= 5

Step3:

LCM(1, 975) = 975

GCD(1, 975) = ( 1 x 975 ) / 975

= 1 / 975

= 1

So, Greatest Common Divisor of 625, 815, 778, 975 is 1
