Given numbers are 384, 783, 257, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(384, 783) = 100224
GCD(384, 783) = ( 384 x 783 ) / 100224
= 384 / 783
= 384
Step2:
LCM(3, 257) = 771
GCD(3, 257) = ( 3 x 257 ) / 771
= 3 / 257
= 3
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 384, 783, 257, 280 is 1
