Given numbers are 105, 138, 800, 571
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 138) = 4830
GCD(105, 138) = ( 105 x 138 ) / 4830
= 105 / 138
= 105
Step2:
LCM(3, 800) = 2400
GCD(3, 800) = ( 3 x 800 ) / 2400
= 3 / 800
= 3
Step3:
LCM(1, 571) = 571
GCD(1, 571) = ( 1 x 571 ) / 571
= 1 / 571
= 1
So, Greatest Common Divisor of 105, 138, 800, 571 is 1
