Given numbers are 788, 781, 139, 783
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(788, 781) = 615428
GCD(788, 781) = ( 788 x 781 ) / 615428
= 788 / 781
= 788
Step2:
LCM(1, 139) = 139
GCD(1, 139) = ( 1 x 139 ) / 139
= 1 / 139
= 1
Step3:
LCM(1, 783) = 783
GCD(1, 783) = ( 1 x 783 ) / 783
= 1 / 783
= 1
So, Greatest Common Divisor of 788, 781, 139, 783 is 1
