Given numbers are 840, 112, 985, 211
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(840, 112) = 1680
GCD(840, 112) = ( 840 x 112 ) / 1680
= 840 / 112
= 840
Step2:
LCM(56, 985) = 55160
GCD(56, 985) = ( 56 x 985 ) / 55160
= 56 / 985
= 56
Step3:
LCM(1, 211) = 211
GCD(1, 211) = ( 1 x 211 ) / 211
= 1 / 211
= 1
So, Greatest Common Divisor of 840, 112, 985, 211 is 1
