Given numbers are 824, 840, 972, 497
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(824, 840) = 86520
GCD(824, 840) = ( 824 x 840 ) / 86520
= 824 / 840
= 824
Step2:
LCM(8, 972) = 1944
GCD(8, 972) = ( 8 x 972 ) / 1944
= 8 / 972
= 8
Step3:
LCM(4, 497) = 1988
GCD(4, 497) = ( 4 x 497 ) / 1988
= 4 / 497
= 4
So, Greatest Common Divisor of 824, 840, 972, 497 is 1
