Given numbers are 842, 918, 79, 409
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 918) = 386478
GCD(842, 918) = ( 842 x 918 ) / 386478
= 842 / 918
= 842
Step2:
LCM(2, 79) = 158
GCD(2, 79) = ( 2 x 79 ) / 158
= 2 / 79
= 2
Step3:
LCM(1, 409) = 409
GCD(1, 409) = ( 1 x 409 ) / 409
= 1 / 409
= 1
So, Greatest Common Divisor of 842, 918, 79, 409 is 1
