Given numbers are 830, 249, 779, 153
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 249) = 2490
GCD(830, 249) = ( 830 x 249 ) / 2490
= 830 / 249
= 830
Step2:
LCM(83, 779) = 64657
GCD(83, 779) = ( 83 x 779 ) / 64657
= 83 / 779
= 83
Step3:
LCM(1, 153) = 153
GCD(1, 153) = ( 1 x 153 ) / 153
= 1 / 153
= 1
So, Greatest Common Divisor of 830, 249, 779, 153 is 1
