Given numbers are 820, 434, 657, 761
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 434) = 177940
GCD(820, 434) = ( 820 x 434 ) / 177940
= 820 / 434
= 820
Step2:
LCM(2, 657) = 1314
GCD(2, 657) = ( 2 x 657 ) / 1314
= 2 / 657
= 2
Step3:
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
= 1 / 761
= 1
So, Greatest Common Divisor of 820, 434, 657, 761 is 1
