Given numbers are 782, 449, 393, 206
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 449) = 351118
GCD(782, 449) = ( 782 x 449 ) / 351118
= 782 / 449
= 782
Step2:
LCM(1, 393) = 393
GCD(1, 393) = ( 1 x 393 ) / 393
= 1 / 393
= 1
Step3:
LCM(1, 206) = 206
GCD(1, 206) = ( 1 x 206 ) / 206
= 1 / 206
= 1
So, Greatest Common Divisor of 782, 449, 393, 206 is 1
