Given numbers are 561, 298, 169, 530
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 298) = 167178
GCD(561, 298) = ( 561 x 298 ) / 167178
= 561 / 298
= 561
Step2:
LCM(1, 169) = 169
GCD(1, 169) = ( 1 x 169 ) / 169
= 1 / 169
= 1
Step3:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
So, Greatest Common Divisor of 561, 298, 169, 530 is 1
