GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(164, 390) = 31980
GCD(164, 390) = ( 164 x 390 ) / 31980
= 164 / 390
= 164
Step2:
LCM(2, 809) = 1618
GCD(2, 809) = ( 2 x 809 ) / 1618
= 2 / 809
= 2
Step3:
LCM(1, 786) = 786
GCD(1, 786) = ( 1 x 786 ) / 786
= 1 / 786
= 1
So, Greatest Common Divisor of 164, 390, 809, 786 is 1
