Given numbers are 820, 635, 970, 919
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 635) = 104140
GCD(820, 635) = ( 820 x 635 ) / 104140
= 820 / 635
= 820
Step2:
LCM(5, 970) = 970
GCD(5, 970) = ( 5 x 970 ) / 970
= 5 / 970
= 5
Step3:
LCM(5, 919) = 4595
GCD(5, 919) = ( 5 x 919 ) / 4595
= 5 / 919
= 5
So, Greatest Common Divisor of 820, 635, 970, 919 is 1
