GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(869, 218) = 189442
GCD(869, 218) = ( 869 x 218 ) / 189442
= 869 / 218
= 869
Step2:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
Step3:
LCM(1, 162) = 162
GCD(1, 162) = ( 1 x 162 ) / 162
= 1 / 162
= 1
So, Greatest Common Divisor of 869, 218, 621, 162 is 1
