Given numbers are 435, 945, 851, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(435, 945) = 27405
GCD(435, 945) = ( 435 x 945 ) / 27405
= 435 / 945
= 435
Step2:
LCM(15, 851) = 12765
GCD(15, 851) = ( 15 x 851 ) / 12765
= 15 / 851
= 15
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 435, 945, 851, 646 is 1
