Given numbers are 400, 806, 669, 139
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(400, 806) = 161200
GCD(400, 806) = ( 400 x 806 ) / 161200
= 400 / 806
= 400
Step2:
LCM(2, 669) = 1338
GCD(2, 669) = ( 2 x 669 ) / 1338
= 2 / 669
= 2
Step3:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
So, Greatest Common Divisor of 400, 806, 669, 139 is 1
