GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(991, 847) = 839377
GCD(991, 847) = ( 991 x 847 ) / 839377
= 991 / 847
= 991
Step2:
LCM(1, 544) = 544
GCD(1, 544) = ( 1 x 544 ) / 544
= 1 / 544
= 1
Step3:
LCM(1, 615) = 615
GCD(1, 615) = ( 1 x 615 ) / 615
= 1 / 615
= 1
So, Greatest Common Divisor of 991, 847, 544, 615 is 1
