Given numbers are 280, 246, 430, 985
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(280, 246) = 34440
GCD(280, 246) = ( 280 x 246 ) / 34440
= 280 / 246
= 280
Step2:
LCM(2, 430) = 430
GCD(2, 430) = ( 2 x 430 ) / 430
= 2 / 430
= 2
Step3:
LCM(2, 985) = 1970
GCD(2, 985) = ( 2 x 985 ) / 1970
= 2 / 985
= 2
So, Greatest Common Divisor of 280, 246, 430, 985 is 1
