Given numbers are 215, 100, 307, 717
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 100) = 4300
GCD(215, 100) = ( 215 x 100 ) / 4300
= 215 / 100
= 215
Step2:
LCM(5, 307) = 1535
GCD(5, 307) = ( 5 x 307 ) / 1535
= 5 / 307
= 5
Step3:
LCM(1, 717) = 717
GCD(1, 717) = ( 1 x 717 ) / 717
= 1 / 717
= 1
So, Greatest Common Divisor of 215, 100, 307, 717 is 1
