Given numbers are 162, 771, 153, 769
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(162, 771) = 41634
GCD(162, 771) = ( 162 x 771 ) / 41634
= 162 / 771
= 162
Step2:
LCM(3, 153) = 153
GCD(3, 153) = ( 3 x 153 ) / 153
= 3 / 153
= 3
Step3:
LCM(3, 769) = 2307
GCD(3, 769) = ( 3 x 769 ) / 2307
= 3 / 769
= 3
So, Greatest Common Divisor of 162, 771, 153, 769 is 1
