Steps to Calculate GCD of 397, 635, 761, 781 using LCM Formula
Given numbers are 397, 635, 761, 781
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(397, 635) = 252095
GCD(397, 635) = ( 397 x 635 ) / 252095
= 397 / 635
= 397
Step2:
LCM(1, 761) = 761
GCD(1, 761) = ( 1 x 761 ) / 761
= 1 / 761
= 1
Step3:
LCM(1, 781) = 781
GCD(1, 781) = ( 1 x 781 ) / 781
= 1 / 781
= 1
So, Greatest Common Divisor of 397, 635, 761, 781 is 1
