Given numbers are 893, 642, 247, 965
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(893, 642) = 573306
GCD(893, 642) = ( 893 x 642 ) / 573306
= 893 / 642
= 893
Step2:
LCM(1, 247) = 247
GCD(1, 247) = ( 1 x 247 ) / 247
= 1 / 247
= 1
Step3:
LCM(1, 965) = 965
GCD(1, 965) = ( 1 x 965 ) / 965
= 1 / 965
= 1
So, Greatest Common Divisor of 893, 642, 247, 965 is 1
