GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(169, 390) = 5070
GCD(169, 390) = ( 169 x 390 ) / 5070
= 169 / 390
= 169
Step2:
LCM(13, 817) = 10621
GCD(13, 817) = ( 13 x 817 ) / 10621
= 13 / 817
= 13
Step3:
LCM(1, 863) = 863
GCD(1, 863) = ( 1 x 863 ) / 863
= 1 / 863
= 1
So, Greatest Common Divisor of 169, 390, 817, 863 is 1
