Given numbers are 131, 209, 402, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(131, 209) = 27379
GCD(131, 209) = ( 131 x 209 ) / 27379
= 131 / 209
= 131
Step2:
LCM(1, 402) = 402
GCD(1, 402) = ( 1 x 402 ) / 402
= 1 / 402
= 1
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 131, 209, 402, 865 is 1
