Given numbers are 665, 646, 892, 732
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(665, 646) = 22610
GCD(665, 646) = ( 665 x 646 ) / 22610
= 665 / 646
= 665
Step2:
LCM(19, 892) = 16948
GCD(19, 892) = ( 19 x 892 ) / 16948
= 19 / 892
= 19
Step3:
LCM(1, 732) = 732
GCD(1, 732) = ( 1 x 732 ) / 732
= 1 / 732
= 1
So, Greatest Common Divisor of 665, 646, 892, 732 is 1
