Given numbers are 817, 471, 155, 570
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(817, 471) = 384807
GCD(817, 471) = ( 817 x 471 ) / 384807
= 817 / 471
= 817
Step2:
LCM(1, 155) = 155
GCD(1, 155) = ( 1 x 155 ) / 155
= 1 / 155
= 1
Step3:
LCM(1, 570) = 570
GCD(1, 570) = ( 1 x 570 ) / 570
= 1 / 570
= 1
So, Greatest Common Divisor of 817, 471, 155, 570 is 1
