Given numbers are 287, 398, 784, 368
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 398) = 114226
GCD(287, 398) = ( 287 x 398 ) / 114226
= 287 / 398
= 287
Step2:
LCM(1, 784) = 784
GCD(1, 784) = ( 1 x 784 ) / 784
= 1 / 784
= 1
Step3:
LCM(1, 368) = 368
GCD(1, 368) = ( 1 x 368 ) / 368
= 1 / 368
= 1
So, Greatest Common Divisor of 287, 398, 784, 368 is 1
