Given numbers are 803, 957, 687, 120
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(803, 957) = 69861
GCD(803, 957) = ( 803 x 957 ) / 69861
= 803 / 957
= 803
Step2:
LCM(11, 687) = 7557
GCD(11, 687) = ( 11 x 687 ) / 7557
= 11 / 687
= 11
Step3:
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
= 1 / 120
= 1
So, Greatest Common Divisor of 803, 957, 687, 120 is 1
