Given numbers are 824, 720, 619, 842
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(824, 720) = 74160
GCD(824, 720) = ( 824 x 720 ) / 74160
= 824 / 720
= 824
Step2:
LCM(8, 619) = 4952
GCD(8, 619) = ( 8 x 619 ) / 4952
= 8 / 619
= 8
Step3:
LCM(1, 842) = 842
GCD(1, 842) = ( 1 x 842 ) / 842
= 1 / 842
= 1
So, Greatest Common Divisor of 824, 720, 619, 842 is 1
