GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(547, 821) = 449087
GCD(547, 821) = ( 547 x 821 ) / 449087
= 547 / 821
= 547
Step2:
LCM(1, 539) = 539
GCD(1, 539) = ( 1 x 539 ) / 539
= 1 / 539
= 1
Step3:
LCM(1, 430) = 430
GCD(1, 430) = ( 1 x 430 ) / 430
= 1 / 430
= 1
So, Greatest Common Divisor of 547, 821, 539, 430 is 1
