Given numbers are 215, 101, 526, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(215, 101) = 21715
GCD(215, 101) = ( 215 x 101 ) / 21715
= 215 / 101
= 215
Step2:
LCM(1, 526) = 526
GCD(1, 526) = ( 1 x 526 ) / 526
= 1 / 526
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 215, 101, 526, 690 is 1
