Given numbers are 662, 215, 721, 985
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(662, 215) = 142330
GCD(662, 215) = ( 662 x 215 ) / 142330
= 662 / 215
= 662
Step2:
LCM(1, 721) = 721
GCD(1, 721) = ( 1 x 721 ) / 721
= 1 / 721
= 1
Step3:
LCM(1, 985) = 985
GCD(1, 985) = ( 1 x 985 ) / 985
= 1 / 985
= 1
So, Greatest Common Divisor of 662, 215, 721, 985 is 1
