Given numbers are 345, 290, 212, 844
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(345, 290) = 20010
GCD(345, 290) = ( 345 x 290 ) / 20010
= 345 / 290
= 345
Step2:
LCM(5, 212) = 1060
GCD(5, 212) = ( 5 x 212 ) / 1060
= 5 / 212
= 5
Step3:
LCM(1, 844) = 844
GCD(1, 844) = ( 1 x 844 ) / 844
= 1 / 844
= 1
So, Greatest Common Divisor of 345, 290, 212, 844 is 1
