Given numbers are 842, 641, 768, 651
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(842, 641) = 539722
GCD(842, 641) = ( 842 x 641 ) / 539722
= 842 / 641
= 842
Step2:
LCM(1, 768) = 768
GCD(1, 768) = ( 1 x 768 ) / 768
= 1 / 768
= 1
Step3:
LCM(1, 651) = 651
GCD(1, 651) = ( 1 x 651 ) / 651
= 1 / 651
= 1
So, Greatest Common Divisor of 842, 641, 768, 651 is 1
