GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(615, 220) = 27060
GCD(615, 220) = ( 615 x 220 ) / 27060
= 615 / 220
= 615
Step2:
LCM(5, 889) = 4445
GCD(5, 889) = ( 5 x 889 ) / 4445
= 5 / 889
= 5
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 615, 220, 889, 847 is 1
