Given numbers are 820, 122, 797, 542
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 122) = 50020
GCD(820, 122) = ( 820 x 122 ) / 50020
= 820 / 122
= 820
Step2:
LCM(2, 797) = 1594
GCD(2, 797) = ( 2 x 797 ) / 1594
= 2 / 797
= 2
Step3:
LCM(1, 542) = 542
GCD(1, 542) = ( 1 x 542 ) / 542
= 1 / 542
= 1
So, Greatest Common Divisor of 820, 122, 797, 542 is 1
