Given numbers are 125, 780, 843, 838
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(125, 780) = 19500
GCD(125, 780) = ( 125 x 780 ) / 19500
= 125 / 780
= 125
Step2:
LCM(5, 843) = 4215
GCD(5, 843) = ( 5 x 843 ) / 4215
= 5 / 843
= 5
Step3:
LCM(1, 838) = 838
GCD(1, 838) = ( 1 x 838 ) / 838
= 1 / 838
= 1
So, Greatest Common Divisor of 125, 780, 843, 838 is 1
