Given numbers are 521, 530, 426, 800
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(521, 530) = 276130
GCD(521, 530) = ( 521 x 530 ) / 276130
= 521 / 530
= 521
Step2:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
Step3:
LCM(1, 800) = 800
GCD(1, 800) = ( 1 x 800 ) / 800
= 1 / 800
= 1
So, Greatest Common Divisor of 521, 530, 426, 800 is 1
