Given numbers are 798, 266, 120, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(798, 266) = 798
GCD(798, 266) = ( 798 x 266 ) / 798
= 798 / 266
= 798
Step2:
LCM(266, 120) = 15960
GCD(266, 120) = ( 266 x 120 ) / 15960
= 266 / 120
= 266
Step3:
LCM(2, 781) = 1562
GCD(2, 781) = ( 2 x 781 ) / 1562
= 2 / 781
= 2
So, Greatest Common Divisor of 798, 266, 120, 781 is 1
