Given numbers are 705, 771, 971, 396
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(705, 771) = 181185
GCD(705, 771) = ( 705 x 771 ) / 181185
= 705 / 771
= 705
Step2:
LCM(3, 971) = 2913
GCD(3, 971) = ( 3 x 971 ) / 2913
= 3 / 971
= 3
Step3:
LCM(1, 396) = 396
GCD(1, 396) = ( 1 x 396 ) / 396
= 1 / 396
= 1
So, Greatest Common Divisor of 705, 771, 971, 396 is 1
