Given numbers are 691, 423, 852, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 423) = 292293
GCD(691, 423) = ( 691 x 423 ) / 292293
= 691 / 423
= 691
Step2:
LCM(1, 852) = 852
GCD(1, 852) = ( 1 x 852 ) / 852
= 1 / 852
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 691, 423, 852, 781 is 1
