GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(961, 249) = 239289
GCD(961, 249) = ( 961 x 249 ) / 239289
= 961 / 249
= 961
Step2:
LCM(1, 901) = 901
GCD(1, 901) = ( 1 x 901 ) / 901
= 1 / 901
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 961, 249, 901, 781 is 1
