Given numbers are 991, 315, 526, 558
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 315) = 312165
GCD(991, 315) = ( 991 x 315 ) / 312165
= 991 / 315
= 991
Step2:
LCM(1, 526) = 526
GCD(1, 526) = ( 1 x 526 ) / 526
= 1 / 526
= 1
Step3:
LCM(1, 558) = 558
GCD(1, 558) = ( 1 x 558 ) / 558
= 1 / 558
= 1
So, Greatest Common Divisor of 991, 315, 526, 558 is 1
