GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(558, 637) = 355446
GCD(558, 637) = ( 558 x 637 ) / 355446
= 558 / 637
= 558
Step2:
LCM(1, 281) = 281
GCD(1, 281) = ( 1 x 281 ) / 281
= 1 / 281
= 1
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 558, 637, 281, 820 is 1
