Given numbers are 698, 306, 823, 836
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(698, 306) = 106794
GCD(698, 306) = ( 698 x 306 ) / 106794
= 698 / 306
= 698
Step2:
LCM(2, 823) = 1646
GCD(2, 823) = ( 2 x 823 ) / 1646
= 2 / 823
= 2
Step3:
LCM(1, 836) = 836
GCD(1, 836) = ( 1 x 836 ) / 836
= 1 / 836
= 1
So, Greatest Common Divisor of 698, 306, 823, 836 is 1
