Given numbers are 781, 672, 795, 678
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(781, 672) = 524832
GCD(781, 672) = ( 781 x 672 ) / 524832
= 781 / 672
= 781
Step2:
LCM(1, 795) = 795
GCD(1, 795) = ( 1 x 795 ) / 795
= 1 / 795
= 1
Step3:
LCM(1, 678) = 678
GCD(1, 678) = ( 1 x 678 ) / 678
= 1 / 678
= 1
So, Greatest Common Divisor of 781, 672, 795, 678 is 1
