Given numbers are 985, 615, 651, 163
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(985, 615) = 121155
GCD(985, 615) = ( 985 x 615 ) / 121155
= 985 / 615
= 985
Step2:
LCM(5, 651) = 3255
GCD(5, 651) = ( 5 x 651 ) / 3255
= 5 / 651
= 5
Step3:
LCM(1, 163) = 163
GCD(1, 163) = ( 1 x 163 ) / 163
= 1 / 163
= 1
So, Greatest Common Divisor of 985, 615, 651, 163 is 1
