Given numbers are 618, 438, 823, 785
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(618, 438) = 45114
GCD(618, 438) = ( 618 x 438 ) / 45114
= 618 / 438
= 618
Step2:
LCM(6, 823) = 4938
GCD(6, 823) = ( 6 x 823 ) / 4938
= 6 / 823
= 6
Step3:
LCM(1, 785) = 785
GCD(1, 785) = ( 1 x 785 ) / 785
= 1 / 785
= 1
So, Greatest Common Divisor of 618, 438, 823, 785 is 1
