Given numbers are 805, 661, 213, 569
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(805, 661) = 532105
GCD(805, 661) = ( 805 x 661 ) / 532105
= 805 / 661
= 805
Step2:
LCM(1, 213) = 213
GCD(1, 213) = ( 1 x 213 ) / 213
= 1 / 213
= 1
Step3:
LCM(1, 569) = 569
GCD(1, 569) = ( 1 x 569 ) / 569
= 1 / 569
= 1
So, Greatest Common Divisor of 805, 661, 213, 569 is 1
