Steps to Calculate GCD of 436, 635, 21, 807 using LCM Formula
Given numbers are 436, 635, 21, 807
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(436, 635) = 276860
GCD(436, 635) = ( 436 x 635 ) / 276860
= 436 / 635
= 436
Step2:
LCM(1, 21) = 21
GCD(1, 21) = ( 1 x 21 ) / 21
= 1 / 21
= 1
Step3:
LCM(1, 807) = 807
GCD(1, 807) = ( 1 x 807 ) / 807
= 1 / 807
= 1
So, Greatest Common Divisor of 436, 635, 21, 807 is 1
