Given numbers are 853, 520, 215, 580
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(853, 520) = 443560
GCD(853, 520) = ( 853 x 520 ) / 443560
= 853 / 520
= 853
Step2:
LCM(1, 215) = 215
GCD(1, 215) = ( 1 x 215 ) / 215
= 1 / 215
= 1
Step3:
LCM(1, 580) = 580
GCD(1, 580) = ( 1 x 580 ) / 580
= 1 / 580
= 1
So, Greatest Common Divisor of 853, 520, 215, 580 is 1
