Given numbers are 868, 830, 656, 239
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 830) = 360220
GCD(868, 830) = ( 868 x 830 ) / 360220
= 868 / 830
= 868
Step2:
LCM(2, 656) = 656
GCD(2, 656) = ( 2 x 656 ) / 656
= 2 / 656
= 2
Step3:
LCM(2, 239) = 478
GCD(2, 239) = ( 2 x 239 ) / 478
= 2 / 239
= 2
So, Greatest Common Divisor of 868, 830, 656, 239 is 1
