Given numbers are 831, 669, 482, 138
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(831, 669) = 185313
GCD(831, 669) = ( 831 x 669 ) / 185313
= 831 / 669
= 831
Step2:
LCM(3, 482) = 1446
GCD(3, 482) = ( 3 x 482 ) / 1446
= 3 / 482
= 3
Step3:
LCM(1, 138) = 138
GCD(1, 138) = ( 1 x 138 ) / 138
= 1 / 138
= 1
So, Greatest Common Divisor of 831, 669, 482, 138 is 1
