Given numbers are 195, 210, 787, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(195, 210) = 2730
GCD(195, 210) = ( 195 x 210 ) / 2730
= 195 / 210
= 195
Step2:
LCM(15, 787) = 11805
GCD(15, 787) = ( 15 x 787 ) / 11805
= 15 / 787
= 15
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 195, 210, 787, 781 is 1
