Given numbers are 862, 162, 671, 620
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(862, 162) = 69822
GCD(862, 162) = ( 862 x 162 ) / 69822
= 862 / 162
= 862
Step2:
LCM(2, 671) = 1342
GCD(2, 671) = ( 2 x 671 ) / 1342
= 2 / 671
= 2
Step3:
LCM(1, 620) = 620
GCD(1, 620) = ( 1 x 620 ) / 620
= 1 / 620
= 1
So, Greatest Common Divisor of 862, 162, 671, 620 is 1
