Given numbers are 646, 398, 851, 892
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(646, 398) = 128554
GCD(646, 398) = ( 646 x 398 ) / 128554
= 646 / 398
= 646
Step2:
LCM(2, 851) = 1702
GCD(2, 851) = ( 2 x 851 ) / 1702
= 2 / 851
= 2
Step3:
LCM(1, 892) = 892
GCD(1, 892) = ( 1 x 892 ) / 892
= 1 / 892
= 1
So, Greatest Common Divisor of 646, 398, 851, 892 is 1
