GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 917) = 772114
GCD(842, 917) = ( 842 x 917 ) / 772114
= 842 / 917
= 842
Step2:
LCM(1, 740) = 740
GCD(1, 740) = ( 1 x 740 ) / 740
= 1 / 740
= 1
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 842, 917, 740, 646 is 1
