Given numbers are 546, 405, 430, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(546, 405) = 73710
GCD(546, 405) = ( 546 x 405 ) / 73710
= 546 / 405
= 546
Step2:
LCM(3, 430) = 1290
GCD(3, 430) = ( 3 x 430 ) / 1290
= 3 / 430
= 3
Step3:
LCM(1, 991) = 991
GCD(1, 991) = ( 1 x 991 ) / 991
= 1 / 991
= 1
So, Greatest Common Divisor of 546, 405, 430, 991 is 1
