Given numbers are 206, 286, 357, 730
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(206, 286) = 29458
GCD(206, 286) = ( 206 x 286 ) / 29458
= 206 / 286
= 206
Step2:
LCM(2, 357) = 714
GCD(2, 357) = ( 2 x 357 ) / 714
= 2 / 357
= 2
Step3:
LCM(1, 730) = 730
GCD(1, 730) = ( 1 x 730 ) / 730
= 1 / 730
= 1
So, Greatest Common Divisor of 206, 286, 357, 730 is 1
