Given numbers are 615, 440, 811, 788
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 440) = 54120
GCD(615, 440) = ( 615 x 440 ) / 54120
= 615 / 440
= 615
Step2:
LCM(5, 811) = 4055
GCD(5, 811) = ( 5 x 811 ) / 4055
= 5 / 811
= 5
Step3:
LCM(1, 788) = 788
GCD(1, 788) = ( 1 x 788 ) / 788
= 1 / 788
= 1
So, Greatest Common Divisor of 615, 440, 811, 788 is 1
