Given numbers are 256, 780, 47, 524
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(256, 780) = 49920
GCD(256, 780) = ( 256 x 780 ) / 49920
= 256 / 780
= 256
Step2:
LCM(4, 47) = 188
GCD(4, 47) = ( 4 x 47 ) / 188
= 4 / 47
= 4
Step3:
LCM(1, 524) = 524
GCD(1, 524) = ( 1 x 524 ) / 524
= 1 / 524
= 1
So, Greatest Common Divisor of 256, 780, 47, 524 is 1
