Given numbers are 280, 452, 832, 857
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 452) = 31640
GCD(280, 452) = ( 280 x 452 ) / 31640
= 280 / 452
= 280
Step2:
LCM(4, 832) = 832
GCD(4, 832) = ( 4 x 832 ) / 832
= 4 / 832
= 4
Step3:
LCM(4, 857) = 3428
GCD(4, 857) = ( 4 x 857 ) / 3428
= 4 / 857
= 4
So, Greatest Common Divisor of 280, 452, 832, 857 is 1
