Given numbers are 860, 215, 491, 670
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(860, 215) = 860
GCD(860, 215) = ( 860 x 215 ) / 860
= 860 / 215
= 860
Step2:
LCM(215, 491) = 105565
GCD(215, 491) = ( 215 x 491 ) / 105565
= 215 / 491
= 215
Step3:
LCM(1, 670) = 670
GCD(1, 670) = ( 1 x 670 ) / 670
= 1 / 670
= 1
So, Greatest Common Divisor of 860, 215, 491, 670 is 1
