Given numbers are 820, 970, 709, 664
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 970) = 79540
GCD(820, 970) = ( 820 x 970 ) / 79540
= 820 / 970
= 820
Step2:
LCM(10, 709) = 7090
GCD(10, 709) = ( 10 x 709 ) / 7090
= 10 / 709
= 10
Step3:
LCM(1, 664) = 664
GCD(1, 664) = ( 1 x 664 ) / 664
= 1 / 664
= 1
So, Greatest Common Divisor of 820, 970, 709, 664 is 1
