Given numbers are 309, 437, 802, 206
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(309, 437) = 135033
GCD(309, 437) = ( 309 x 437 ) / 135033
= 309 / 437
= 309
Step2:
LCM(1, 802) = 802
GCD(1, 802) = ( 1 x 802 ) / 802
= 1 / 802
= 1
Step3:
LCM(1, 206) = 206
GCD(1, 206) = ( 1 x 206 ) / 206
= 1 / 206
= 1
So, Greatest Common Divisor of 309, 437, 802, 206 is 1
