Given numbers are 438, 837, 847, 865
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(438, 837) = 122202
GCD(438, 837) = ( 438 x 837 ) / 122202
= 438 / 837
= 438
Step2:
LCM(3, 847) = 2541
GCD(3, 847) = ( 3 x 847 ) / 2541
= 3 / 847
= 3
Step3:
LCM(1, 865) = 865
GCD(1, 865) = ( 1 x 865 ) / 865
= 1 / 865
= 1
So, Greatest Common Divisor of 438, 837, 847, 865 is 1
