Given numbers are 858, 274, 280, 427
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 274) = 117546
GCD(858, 274) = ( 858 x 274 ) / 117546
= 858 / 274
= 858
Step2:
LCM(2, 280) = 280
GCD(2, 280) = ( 2 x 280 ) / 280
= 2 / 280
= 2
Step3:
LCM(2, 427) = 854
GCD(2, 427) = ( 2 x 427 ) / 854
= 2 / 427
= 2
So, Greatest Common Divisor of 858, 274, 280, 427 is 1
