Given numbers are 658, 245, 518, 853
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 245) = 23030
GCD(658, 245) = ( 658 x 245 ) / 23030
= 658 / 245
= 658
Step2:
LCM(7, 518) = 518
GCD(7, 518) = ( 7 x 518 ) / 518
= 7 / 518
= 7
Step3:
LCM(7, 853) = 5971
GCD(7, 853) = ( 7 x 853 ) / 5971
= 7 / 853
= 7
So, Greatest Common Divisor of 658, 245, 518, 853 is 1
