Given numbers are 670, 266, 620, 919
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(670, 266) = 89110
GCD(670, 266) = ( 670 x 266 ) / 89110
= 670 / 266
= 670
Step2:
LCM(2, 620) = 620
GCD(2, 620) = ( 2 x 620 ) / 620
= 2 / 620
= 2
Step3:
LCM(2, 919) = 1838
GCD(2, 919) = ( 2 x 919 ) / 1838
= 2 / 919
= 2
So, Greatest Common Divisor of 670, 266, 620, 919 is 1
