Given numbers are 561, 545, 497, 160
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(561, 545) = 305745
GCD(561, 545) = ( 561 x 545 ) / 305745
= 561 / 545
= 561
Step2:
LCM(1, 497) = 497
GCD(1, 497) = ( 1 x 497 ) / 497
= 1 / 497
= 1
Step3:
LCM(1, 160) = 160
GCD(1, 160) = ( 1 x 160 ) / 160
= 1 / 160
= 1
So, Greatest Common Divisor of 561, 545, 497, 160 is 1
