Given numbers are 862, 990, 204, 693
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 990) = 426690
GCD(862, 990) = ( 862 x 990 ) / 426690
= 862 / 990
= 862
Step2:
LCM(2, 204) = 204
GCD(2, 204) = ( 2 x 204 ) / 204
= 2 / 204
= 2
Step3:
LCM(2, 693) = 1386
GCD(2, 693) = ( 2 x 693 ) / 1386
= 2 / 693
= 2
So, Greatest Common Divisor of 862, 990, 204, 693 is 1
