Given numbers are 207, 705, 288, 772
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(207, 705) = 48645
GCD(207, 705) = ( 207 x 705 ) / 48645
= 207 / 705
= 207
Step2:
LCM(3, 288) = 288
GCD(3, 288) = ( 3 x 288 ) / 288
= 3 / 288
= 3
Step3:
LCM(3, 772) = 2316
GCD(3, 772) = ( 3 x 772 ) / 2316
= 3 / 772
= 3
So, Greatest Common Divisor of 207, 705, 288, 772 is 1
