GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(762, 186) = 23622
GCD(762, 186) = ( 762 x 186 ) / 23622
= 762 / 186
= 762
Step2:
LCM(6, 390) = 390
GCD(6, 390) = ( 6 x 390 ) / 390
= 6 / 390
= 6
Step3:
LCM(6, 771) = 1542
GCD(6, 771) = ( 6 x 771 ) / 1542
= 6 / 771
= 6
So, Greatest Common Divisor of 762, 186, 390, 771 is 3
