Given numbers are 230, 115, 785, 698
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(230, 115) = 230
GCD(230, 115) = ( 230 x 115 ) / 230
= 230 / 115
= 230
Step2:
LCM(115, 785) = 18055
GCD(115, 785) = ( 115 x 785 ) / 18055
= 115 / 785
= 115
Step3:
LCM(5, 698) = 3490
GCD(5, 698) = ( 5 x 698 ) / 3490
= 5 / 698
= 5
So, Greatest Common Divisor of 230, 115, 785, 698 is 1
