Given numbers are 620, 861, 911, 159
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(620, 861) = 533820
GCD(620, 861) = ( 620 x 861 ) / 533820
= 620 / 861
= 620
Step2:
LCM(1, 911) = 911
GCD(1, 911) = ( 1 x 911 ) / 911
= 1 / 911
= 1
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 620, 861, 911, 159 is 1
