GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 578) = 243338
GCD(842, 578) = ( 842 x 578 ) / 243338
= 842 / 578
= 842
Step2:
LCM(2, 579) = 1158
GCD(2, 579) = ( 2 x 579 ) / 1158
= 2 / 579
= 2
Step3:
LCM(1, 179) = 179
GCD(1, 179) = ( 1 x 179 ) / 179
= 1 / 179
= 1
So, Greatest Common Divisor of 842, 578, 579, 179 is 1
