Given numbers are 822, 615, 697, 212
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(822, 615) = 168510
GCD(822, 615) = ( 822 x 615 ) / 168510
= 822 / 615
= 822
Step2:
LCM(3, 697) = 2091
GCD(3, 697) = ( 3 x 697 ) / 2091
= 3 / 697
= 3
Step3:
LCM(1, 212) = 212
GCD(1, 212) = ( 1 x 212 ) / 212
= 1 / 212
= 1
So, Greatest Common Divisor of 822, 615, 697, 212 is 1
