Given numbers are 843, 661, 149, 762
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(843, 661) = 557223
GCD(843, 661) = ( 843 x 661 ) / 557223
= 843 / 661
= 843
Step2:
LCM(1, 149) = 149
GCD(1, 149) = ( 1 x 149 ) / 149
= 1 / 149
= 1
Step3:
LCM(1, 762) = 762
GCD(1, 762) = ( 1 x 762 ) / 762
= 1 / 762
= 1
So, Greatest Common Divisor of 843, 661, 149, 762 is 1
