Given numbers are 858, 216, 842, 493
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 216) = 30888
GCD(858, 216) = ( 858 x 216 ) / 30888
= 858 / 216
= 858
Step2:
LCM(6, 842) = 2526
GCD(6, 842) = ( 6 x 842 ) / 2526
= 6 / 842
= 6
Step3:
LCM(2, 493) = 986
GCD(2, 493) = ( 2 x 493 ) / 986
= 2 / 493
= 2
So, Greatest Common Divisor of 858, 216, 842, 493 is 1
